dd mrsas(4) driver from LSI official support of newer MegaRAID SAS
cards. LSI has been maintaining this driver outside of the FreeBSD
tree. It overlaps support of ThunderBolt and Invader cards that mfi(4)
supports. By default mfi(4) will attach to cards. If the tunable:
hw.mfi.mrsas_enable=1
is set then mfi(4) will not probe and attach to these newer cards and
allow mrsas(4) to attach. So by default this driver will not effect
a FreeBSD system unless mfi(4) is removed from the kernel or the
tunable is enabled.

mrsas(4) attaches disks to the CAM layer so it depends on CAM and devices
show up as /dev/daX. mfiutil(8) does not work with mrsas. The FreeBSD
version of MegaCli and StorCli from LSI do work with mrsas. It appears
that StorCli only works with mrsas. MegaCli appears to work with mfi(4)
and mrsas(4).

It would be good to add mfiutil(4) support to mrsas, emulations modes,
kernel logging, device aliases to ease the transition between mfi(4)
and mrsas(4).

Style issues should be resolved by LSI when they get committers approved.
The plan is get this driver in FreeBSD 9.3 to improve HW support.

Thanks to LSI for developing, testing and working with FreeBSD to
make this driver co-exist in FreeBSD. This improves the overall
support of MegaRAID SAS.

Bring in the mpr(4) driver for LSI's MPT3 12Gb SAS controllers.

This is derived from the mps(4) driver, but it supports only the 12Gb
IT and IR hardware including the SAS 3004, SAS 3008 and SAS 3108.

Some notes about this driver:
o The 12Gb hardware can do "FastPath" I/O, and that capability is included in
this driver.

o WarpDrive functionality has been removed, since it isn't supported in
the 12Gb driver interface.

o The Scatter/Gather list handling code is significantly different between
the 6Gb and 12Gb hardware. The 12Gb boards support IEEE Scatter/Gather
lists.

Thanks to LSI for developing and testing this driver for FreeBSD.

Adjust #if statements inside mprsas_send_smpcmd() to more accurately
reflect when unmapped I/O support was added.

For FreeBSD 10, it arrived just prior to __FreeBSD_version 1000028.
For FreeBSD 9, it arrived just prior to __FreeBSD_version 902001.

Also, fix compiler warnings in mprsas_send_smpcmd() that happen in the
i386 PAE build for non-unmapped I/O builds. These were fixed in mps(4)
in revision 241145, but didn't make it into the mpr(4) driver. This
change should only affect FreeBSD versions outside the above revisions,
and thus doesn't affect head.

Fix a problem with async notifications in the mpr(4) driver.

This problem only occurs on versions of FreeBSD prior to the recent CAM
locking changes. (i.e. stable/9 and older versions of stable/10) This
change should be a no-op for head and stable/10.

If a path isn't specified, xpt_register_async() will create a fully
wildcarded path and acquire a lock (the XPT lock in older versions,
and via xpt_path_lock() in newer versions) to call xpt_action() for the
XPT_SASYNC_CB CCB. It will then drop the lock and if the requested event
includes AC_FOUND_DEVICE or AC_PATH_REGISTERED, it will get the caller up
to date with any device arrivals or path registrations.

The issue is that before the locking changes, each SIM lock would get
acquired in turn during the EDT tree traversal process. If a path is
specified for xpt_register_async(), it won't acquire and drop its own lock,
but instead expects the caller to hold its own SIM lock. That works for
the first part of xpt_register_async(), but causes a recursive lock
acquisition once the EDT traversal happens and it comes to the SIM in
question. And it isn't possible to call xpt_action() without holding a SIM
lock.

The locking changes fix this by using the XPT topology lock for EDT
traversal, so it is no longer an issue to hold the SIM lock while calling
xpt_register_async().

The solution for FreeBSD versions before the locking changes is to request
notification of all device arrivals (so we pass a NULL path into
xpt_register_async()) and then filter out the arrivals that are not ours.

paper "Revisiting TCP Congestion Control using Delay Gradients" by David Hayes
and Grenville Armitage. It is implemented as a kernel module compatible with the
modular congestion control framework.

CDG is a hybrid congestion control algorithm which reacts to both packet loss
and inferred queuing delay. It attempts to operate as a delay-based algorithm
where possible, but utilises heuristics to detect loss-based TCP cross traffic
and will compete effectively as required. CDG is therefore incrementally
deployable and suitable for use on shared networks.

Many thanks to Areca for continuing to support FreeBSD.

Submitted by: 黃清隆 <ching2048 areca com tw>

r245468, r245517, r245518, r245520, r245567, r245933, r245935, r245936,

r247347, r247355, and r241733.

Note that TCP_OFFLOAD is not enabled in 9 yet and so some of these MFCs
don't really affect functionality. But they do help future MFCs
(related to TCP_OFFLOAD or not) by minimizing diffs with the driver in
head.

r245243:
cxgbe(4): updates to the configuration file that controls how hardware
resources are partitioned.

- Reduce the number of virtual interfaces reserved for PF4. This leaves
spare room in the source MAC table and allows the driver to setup
filters that rewrite the source MAC address.

- Reduce the number of filters and use the freed up space for the CLIP
(Compressed Local IPv6 addresses) table. This is a prerequisite for
IPv6 TOE support which will follow separately in a series of commits.

r245274:
cxgbe(4): Add functions to help synchronize "slow" operations (those not
on the fast data path) and use them instead of frobbing the adapter lock
and busy flag directly.

Other changes made while reworking all slow operations:
- Wait for the reply to a filter request (add/delete). This guarantees
that the operation is complete by the time the ioctl returns.
- Tidy up the tid_info structure.
- Do not allow the tx queue size to be set to something that's not a
power of 2.

r245276:
Overhaul the stid allocator so that it can be used for IPv6 servers
too. The entry for an IPv6 server in the TCAM takes up the equivalent
of two ordinary stids and must be properly aligned too.

r245434:
cxgbe(4): Updates to the hardware L2 table management code.

- Add full support for IPv6 addresses.

- Read the size of the L2 table during attach. Do not assume that PCIe
physical function 4 of the card has all of the table to itself.

- Use FNV instead of Jenkins to hash L3 addresses and drop the private
copy of jhash.h from the driver.

r245441:
cxgbe/tom: Miscellaneous updates for TOE+IPv6 support (more to follow).

- Teach find_best_mtu_idx() to deal with IPv6 endpoints.

- Install correct protosw in offloaded TCP/IPv6 sockets when DDP is
enabled.

- Move set_tcp_ddp_ulp_mode to t4_tom.c so that t4_tom.h can be included
without having to drag in t4_msg.h too. This was bothering the iWARP
driver for some reason.

r245448:
cxgbe/tom: Basic CLIP table management.

This is the Compressed Local IPv6 table on the chip. To save space, the
chip uses an index into this table instead of a full IPv6 address in
some of its hardware data structures.

For now the driver fills this table with all the local IPv6 addresses
that it sees at the time the table is initialized. I'll improve this
later so that the table is updated whenever new IPv6 addresses are
configured or existing ones deleted.

r245467:
cxgbe/tom: Add support for fully offloaded TCP/IPv6 connections (active open).

r245468:
cxgbe/tom: Add support for fully offloaded TCP/IPv6 connections (passive open).

r245517:
cxgbe: Fix the for_each_foo macros -- the last argument should not share
its name with any member of struct sge.

r245518:
cxgbe: Do a more thorough job in the CLEAR_STATS ioctl.

r245520:
Allow "ivlan" (inner VLAN) to be used as an alias for "vlan" when
specifying match criteria. "vlan" continues to be valid here, and it
continues to be valid when deleting, rewriting, inserting, or stacking
an 802.1q tag to a matching packet.

r245567:
cxgbe: Make the for_each macros safer to use by turning them
into a single statement each.

r245933:
cxgbe/tom: List IFCAP_TOE6 as supported now that all the required pieces
are in place. You still have to enable it explicitly, after loading the
t4_tom KLD.

r245935:
Add a couple of missing error codes. Treat CPL_ERR_KEEPALV_NEG_ADVICE as
negative advice and not a fatal error.

r245936:
Force the 404-BT card (4 x 1G) to use the "uwire" configuration file.

r245937:
Install an extra hold on the newly allocated synq entry so that it
cannot be freed while do_pass_accept_req is running. This closes a race
where do_pass_establish on another CPU (the driver chose a different
queue for the new tid) expands the synq entry into a full PCB and then
releases the only hold on it, all while do_pass_accept_req is still
running.

r246093:
Provide a statistic to track the number of drops in each of the port's
txq's buf_ring. The aggregate for all the queues of a port is already
provided in ifnet->if_snd.ifq_drops.

r246385:
Busy-wait when cold.

r246575:
Do not hold locks around hardware context reads.

r247062:
cxgbe(4): Assume that CSUM_TSO in the transmit path implies CSUM_IP and
CSUM_TCP too. They are all set explicitly by the kernel usually.

r247122:
cxgbe(4): Add sysctls to extract debug information from the chip:

dev.t4nex.X.misc.cim_la logic analyzer dump
dev.t4nex.X.misc.cim_qcfg queue configuration
dev.t4nex.X.misc.cim_ibq_xxx inbound queues
dev.t4nex.X.misc.cim_obq_xxx outbound queues

r247289:
cxgbe(4): Update firmware to 1.8.4.0.

r247291:
cxgbe(4): Ask the card's firmware to pad up tiny CPLs by encapsulating
them in a firmware message if it is able to do so. This works out
better for one of the FIFOs in the chip.

r247347:
cxgbe(4): Consider all the API versions of the interfaces exported by
the firmware (instead of just the main firmware version) when evaluating
firmware compatibility. Document the new "hw.cxgbe.fw_install" knob
being introduced here.

This should fix kern/173584 too. Setting hw.cxgbe.fw_install=2 will
mostly do what was requested in the PR but it's a bit more intelligent
in that it won't reinstall the same firmware repeatedly if the knob is
left set.

r247355:
cxgbe(4): Report unusual out of band errors from the firmware.

r241733 (by ed@):
Prefer __containerof() over __member2struct().

The former works better with qualifiers, but also properly type checks

list CPUs in different orders, especially for disabled logical cores. Now
we match ACPI IDs from the MADT with Processor objects, strictly order CPUs

methods for other CPUs, e. g., _PSS for disabled logical core, which may not
exist. Unfortunately, it is known that there are a few systems with buggy
BIOSes that do not have unique ACPI IDs for MADT and Processor objects. To
work around these problems, 'debug.acpi.cpu_unordered' tunable is added.

Add kern.eventtimer.activetick tunable/sysctl, specifying whether each
hardclock() tick should be run on every active CPU, or on only one.

On my tests, avoiding extra interrupts because of this on 8-CPU Core i7
system with HZ=10000 saves about 2% of performance. At this moment option
implemented only for global timers, as reprogramming per-CPU timers is
too expensive now to be compensated by this benefit, especially since we
still have to regularly run hardclock() on at least one active CPU to
update system uptime. For global timer it is quite trivial: timer runs
always, but we just skip IPIs to other CPUs when possible.

Option is enabled by default now, keeping previous behavior, as periodic
hardclock() calls are still used at least to implement setitimer(2) with
ITIMER_VIRTUAL and ITIMER_PROF arguments. But since default schedulers don't
depend on it since r232917, we are much more free to experiment with it.
