The baud rate on CP1201/2/3 devices can be set in one of two ways:
- The USLCOM_SET_BAUD_DIV command (0x01)
- The USLCOM_SET_BAUD_RATE command (0x13)

Devices based on the CP1204 will only accept the latter command, and ignore
the former. As the latter command works on all chips that this driver
supports, switch to always using it.

A slight confusion here is that the previously used command was incorrectly
named USLCOM_BAUD_RATE - even though we no longer use it, rename it to
USLCOM_SET_BAUD_DIV to closer match the name used in the datasheet.

This change reflects a similar change made in the Linux driver, which was
submitted by preston.fick at silabs.com, and has been tested on all of the

MFC r238718: Quirk MS keyboard so that function keys work

The function keys on a Microsoft Natural Egronomic Keyboard 4000 have been
repurposed as "Help", "Undo", "Redo" etc., and a special "F Lock" key is
required to return them to their normal purpose.

This change enables the UQ_KBD_BOOTPROTO quirk for the MS Natural 4000
keyboard to get the keys working again. More extensive changes to the USB
keyboard infrastructure would be needed to fully support the "F Lock" mode
and the extended keys on this keyboard.

MFC r225950:

Add descriptor sense support to CAM, and honor sense residuals properly in
CAM.

Desriptor sense is a new sense data format that originated in SPC-3. Among
other things, it allows for an 8-byte info field, which is necessary to
pass back block numbers larger than 4 bytes.

This change adds a number of new functions to scsi_all.c (and therefore
libcam) that abstract out most access to sense data.

This includes a bump of CAM_VERSION, because the CCB ABI has changed.
Userland programs that use the CAM pass(4) driver will need to be
recompiled.

camcontrol.c: Change uses of scsi_extract_sense() to use
scsi_extract_sense_len().

Use scsi_get_sks() instead of accessing sense key specific
data directly.

scsi_modes: Update the control mode page to the latest version (SPC-4).

scsi_cmds.c,
scsi_target.c: Change references to struct scsi_sense_data to struct
scsi_sense_data_fixed. This should be changed to allow the
user to specify fixed or descriptor sense, and then use
scsi_set_sense_data() to build the sense data.

ps3cdrom.c: Use scsi_set_sense_data() instead of setting sense data
manually.

cam_periph.c: Use scsi_extract_sense_len() instead of using
scsi_extract_sense() or accessing sense data directly.

cam_ccb.h: Bump the CAM_VERSION from 0x15 to 0x16. The change of
struct scsi_sense_data from 32 to 252 bytes changes the
size of struct ccb_scsiio, but not the size of union ccb.
So the version must be bumped to prevent structure
mis-matches.

scsi_all.h: Lots of updated SCSI sense data and other structures.

Add function prototypes for the new sense data functions.

Take out the inline implementation of scsi_extract_sense().
It is now too large to put in a header file.

Add macros to calculate whether fields are present and
filled in fixed and descriptor sense data

scsi_all.c: In scsi_op_desc(), allow the user to pass in NULL inquiry
data, and we'll assume a direct access device in that case.

Changed the SCSI RESERVED sense key name and description
to COMPLETED, as it is now defined in the spec.

Change the error recovery action for a number of read errors
to prevent lots of retries when the drive has said that the
block isn't accessible. This speeds up reconstruction of
the block by any RAID software running on top of the drive
(e.g. ZFS).

In scsi_sense_desc(), allow for invalid sense key numbers.
This allows calling this routine without checking the input
values first.

Change scsi_error_action() to use scsi_extract_sense_len(),
and handle things when invalid asc/ascq values are
encountered.

Add a new routine, scsi_desc_iterate(), that will call the
supplied function for every descriptor in descriptor format
sense data.

Add scsi_set_sense_data(), and scsi_set_sense_data_va(),
which build descriptor and fixed format sense data. They
currently default to fixed format sense data.

Add a number of scsi_get_*() functions, which get different
types of sense data fields from either fixed or descriptor
format sense data, if the data is present.

Add a number of scsi_*_sbuf() functions, which print
formatted versions of various sense data fields. These
functions work for either fixed or descriptor sense.

Add a number of scsi_sense_*_sbuf() functions, which have a
standard calling interface and print the indicated field.
These functions take descriptors only.

Add scsi_sense_desc_sbuf(), which will print a formatted
version of the given sense descriptor.

Pull out a majority of the scsi_sense_sbuf() function and
put it into scsi_sense_only_sbuf(). This allows callers
that don't use struct ccb_scsiio to easily utilize the
printing routines. Revamp that function to handle
descriptor sense and use the new sense fetching and
printing routines.

Move scsi_extract_sense() into scsi_all.c, and implement it
in terms of the new function, scsi_extract_sense_len().
The _len() version takes a length (which should be the
sense length - residual) and can indicate which fields are
present and valid in the sense data.

Add a couple of new scsi_get_*() routines to get the sense
key, asc, and ascq only.

mly.c: Rename struct scsi_sense_data to struct
scsi_sense_data_fixed.

sbp_targ.c: Use the new sense fetching routines to get sense data
instead of accessing it directly.

sbp.c: Change the firewire/SCSI sense data transformation code to
use struct scsi_sense_data_fixed instead of struct
scsi_sense_data. This should be changed later to use
scsi_set_sense_data().

ciss.c: Calculate the sense residual properly. Use
scsi_get_sense_key() to fetch the sense key.

mps_sas.c,
mpt_cam.c: Set the sense residual properly.

iir.c: Use scsi_set_sense_data() instead of building sense data by
hand.

iscsi_subr.c: Use scsi_extract_sense_len() instead of grabbing sense data
directly.

umass.c: Use scsi_set_sense_data() to build sense data.

Grab the sense key using scsi_get_sense_key().

Calculate the sense residual properly.

isp_freebsd.h: Use scsi_get_*() routines to grab asc, ascq, and sense key
values.

Calculate and set the sense residual.

usb: change to one-pass probing of device drivers

This brings USB bus more in line with how newbus is supposed to be used.
Also, because of the two-pass probing the following message was produced
by devd in default configuration when almost any USB device was
connected:
Unknown USB device: vendor <> product <> bus <>
This should be fixed now.

Note that many USB device drivers pass some information from probe
method to attach method via ivars. For this to continue working we rely
on the fact that the subr_bus code calls probe method of a winning driver
again before calling its attach method in the case where multiple
drivers claim to support a device. This is done because device
description is set in successful probe methods and we want to get a correct
device description from a winning driver. So now this logic is re-used
for setting ivars too.

- Remove attempts to implement setting of BMCR_LOOP/MIIF_NOLOOP
(reporting IFM_LOOP based on BMCR_LOOP is left in place though as
it might provide useful for debugging). For most mii(4) drivers it
was unclear whether the PHYs driven by them actually support
loopback or not. Moreover, typically loopback mode also needs to
be activated on the MAC, which none of the Ethernet drivers using
mii(4) implements. Given that loopback media has no real use (and
obviously hardly had a chance to actually work) besides for driver
development (which just loopback mode should be sufficient for
though, i.e one doesn't necessary need support for loopback media)
support for it is just dropped as both NetBSD and OpenBSD already
did quite some time ago.
- Let mii_phy_add_media() also announce the support of IFM_NONE.
- Restructure the PHY entry points to use a structure of entry points
instead of discrete function pointers, and extend this to include
a "reset" entry point. Make sure any PHY-specific reset routine is
always used, and provide one for lxtphy(4) which disables MII
interrupts (as is done for a few other PHYs we have drivers for).
This includes changing NIC drivers which previously just called the
generic mii_phy_reset() to now actually call the PHY-specific reset
routine, which might be crucial in some cases. While at it, the
redundant checks in these NIC drivers for mii->mii_instance not being
zero before calling the reset routines were removed because as soon
as one PHY driver attaches mii->mii_instance is incremented and we
hardly can end up in their media change callbacks etc if no PHY driver
has attached as mii_attach() would have failed in that case and not
attach a miibus(4) instance.
Consequently, NIC drivers now no longer should call mii_phy_reset()
directly, so it was removed from EXPORT_SYMS.
- Add a mii_phy_dev_attach() as a companion helper to mii_phy_dev_probe().
The purpose of that function is to perform the common steps to attach
a PHY driver instance and to hook it up to the miibus(4) instance and to
optionally also handle the probing, addition and initialization of the
supported media. So all a PHY driver without any special requirements
has to do in its bus attach method is to call mii_phy_dev_attach()
along with PHY-specific MIIF_* flags, a pointer to its PHY functions
and the add_media set to one. All PHY drivers were updated to take
advantage of mii_phy_dev_attach() as appropriate. Along with these
changes the capability mask was added to the mii_softc structure so
PHY drivers taking advantage of mii_phy_dev_attach() but still
handling media on their own do not need to fiddle with the MII attach
arguments anyway.
- Keep track of the PHY offset in the mii_softc structure. This is done
for compatibility with NetBSD/OpenBSD.
- Keep track of the PHY's OUI, model and revision in the mii_softc
structure. Several PHY drivers require this information also after
attaching and previously had to wrap their own softc around mii_softc.
NetBSD/OpenBSD also keep track of the model and revision on their
mii_softc structure. All PHY drivers were updated to take advantage
as appropriate.
- Convert the mebers of the MII data structure to unsigned where
appropriate. This is partly inspired by NetBSD/OpenBSD.
- According to IEEE 802.3-2002 the bits actually have to be reversed
when mapping an OUI to the MII ID registers. All PHY drivers and
miidevs where changed as necessary. Actually this now again allows to
largely share miidevs with NetBSD, which fixed this problem already
9 years ago. Consequently miidevs was synced as far as possible.
- Add MIIF_NOMANPAUSE and mii_phy_flowstatus() calls to drivers that
weren't explicitly converted to support flow control before. It's
unclear whether flow control actually works with these but typically
it should and their net behavior should be more correct with these
changes in place than without if the MAC driver sets MIIF_DOPAUSE.

Drivers which rely on net80211 to create the beacon need to call

that certain bits, e.g. TIM, get updated. A call to ieee80211_beacon_alloc()
is not enough because it does not care about flags which can only change
during runtime. By design a beacon is supposed to be allocated only once
while moving into RUN state.

To handle all possible calls to iv_update_beacon() the run_updateslot()
function has been revived and run_updateprot() has been added.
run_updateslot() handles slot time changes and run_updateprot() changes

r184610 changed the way how TX frames are handled on AX88178 and
AX88772 controllers. ASIX added a new feature for AX88178/AX88772
controllers which allows combining multiple TX frames into a single
big frame. This was to overcome one of USB limitation where it
can't generate more than 8k interrupts/sec which in turn means USB
ethernet controllers can not send more than 8k packets per second.
Using ASIX's feature greatly enhanced TX performance(more than 3~4
times) compared to 7.x driver. However it seems r184610 removed
boundary checking for buffered frames which in turn caused
instability issues under certain conditions. In addition, using
ASIX's feature triggered another issue which made USB controller
hang under certain conditions. Restarting ethernet controller
didn't help under this hang condition and unplugging and replugging
the controller was the only solution. I believe there is a silicon
bug in TX frame combining feature on AX88178/AX88772 controllers.

To address these issues, reintroduce the boundary checking for both
AX88178 and AX88772 after copying a frame to USB buffer and do not
use ASIX's multiple frame combining feature. Instead, use USB
controller's multi-frame transmit capability to enhance TX
performance as suggested by Hans[1].
This should fix a long standing axe(4) instability issues reported
on AX88772 and AX88178 controllers. While I'm here remove
unnecessary TX frame length check since upper stack always
guarantee the size of a frame to be less than MCLBYTES.

proper solution which is to not use the TERMINATE pointer, but rather

this up. This patch can increase mass storage read performance
significantly when the IRQ rate is less than 8000 IRQ/s.

Do not setup interrupt endpoint for axe(4).
It seems axe(4) controllers support interrupt endpoint such that
enabling interrupt endpoint generates about 1000 interrupts/sec.
Controllers transfer 8 bytes data through interrupt endpoint and
the data include link UP/DOWN state as well as some PHY related
information. Previously axe(4) didn't use the transferred data and
didn't even try to read the data. Because axe(4) counts on mii(4)
to detect link state changes there is no need to use interrupt
endpoint here.

This change fixes generation of unnecessary interrupts which was
seen when interface is brought to UP.

This commit adds full support for USB 3.0 devices in host and device
mode in the USB core. The patch mostly consists of updating the USB
HUB code to support USB 3.0 HUBs. This patch also add some more USB
controller methods to support more active-alike USB controllers like
the XHCI which needs to be informed about various device state events.

USB 3.0 HUBs are not tested yet, due to lack of hardware, but are
believed to work.

After this update the initial device descriptor is only read twice
when we know that the bMaxPacketSize is too small for a single packet
transfer of this descriptor.

Make upper stack know driver's output status. This change increased
TX performance from 221kpps to 231kpps.

Move updating TX packet counter to the inside of send loop. axe(4)
controllers combine multiple TX requests into single one if there
is room in TX buffer of controller. Updating TX packet counter at
the end of TX completion resulted in incorrect TX packet counter as
axe(4) thought it sent 1 packet. There is no easy way to know how
many combined TX were completed in the callback.
Because this change updates TX packet counter before actual
transmission, it may not be ideal one. But I believe it's better
than showing fake 8kpps under high TX load. With this change, TX
shows 221kpps on Linksus USB200M.

Commit initial version of new XHCI driver which was written from
scratch. This driver adds support for USB3.0 devices. The XHCI
interface is also backwards compatible to USB2.0 and USB1.0 and will

There will be follow-up commits during the coming week to link the
driver into the default kernel build and add missing USB3.0

The following systems are involved:

- DB-88F5182

This overhaul covers the following major changes:

- All integrated peripherals drivers for Marvell ARM SoC, which are
currently in the FreeBSD source tree are reworked and adjusted so they
derive config data out of the device tree blob (instead of hard coded /
tabelarized values).

- Since the common FDT infrastrucutre (fdtbus, simplebus) is used we say
good by to obio / mbus drivers and numerous hard-coded config data.

can be extended to act as system mouse. Meanwhile, it just

The name for the driver is chosen to be the same as in NetBSD,
however, due to different USB stacks this driver isn't a port.
