Implement TX/RX checksum offloading support for ASIX AX88772B
controller.

AX88772B data sheet does not show detailed information about
checksum offloading related things. It seems the controller has
lots of options to support checksum offloading but I failed to
understand why this feature requires so much complex controller
configuration and status bits.
One of major difference between AX88772B and its predecessor is
AX88772B uses a new RX header format when RX checksum offloading is
enabled. It also requires the received length of a frame should be
multiple of 4. Controller will pad necessary bytes to make the
length of received frame to be multiple of 4. It is driver's
responsibility to offset this pad bytes.
Note, AX88772B could be configured to get partial checksum value in
in RX header. This mode uses different RX header format and
currently we don't use that fature.

This change makes axe(4) use driver specific MII attach handler to
override uether(9)'s default MII attach and announce flow-control
capability for AX88178/AX88772A/AX88772B to PHY drivers. It seems
original AX88772 also supports flow-control but I didn't enable it
due to lack of test/access to the controller. The flow-control
threshold parameter is loaded from EEPROM and there is no way to
override this value without reprogramming EEPROM. For AX88772B,
TX/RX IP/TCP/UDP checksum offloading is announced to network stack.
IPv6 and PPPoE checksum offloading is also supported by controller
but we have no way to take advantage of these features.
Driver already knows PHY address so make PHY driver know that
information and remove unnecessary PHY address check used in
miibus_readreg/miibus_writereg callbacks. Also announce AX88178,
AX88772A and AX88772B support VLAN over-sized frame.

While I'm here clean up headers and remove axe_start() in
axe_init() because the link wouldn't be available right after media
change.


# 224020 14-Jul-2011 yongari

Add initial support for AX88772B USB Fast Ethernet. AX88772B
supports IPv4/IPv6 checksum offloading and VLAN tag insertion/
stripping as well as WOL. Because uether does not provide a way
to announce driver specific offload capabilities to upper stack,
checksum offloading support needs more work and will be done in
future.
Special thanks to ASIX for donating sample hardware.

# 213696 11-Oct-2010 yongari

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.

No objections from: hselasky

Bring in USB4BSD, Hans Petter Selasky rework of the USB stack
that includes significant features and SMP safety.

This commit includes a more or less complete rewrite of the *BSD USB
stack, including Host Controller and Device Controller drivers and
updating all existing USB drivers to use the new USB API:

1) A brief feature list:

- A new and mutex enabled USB API.

- Many USB drivers are now running Giant free.

- Linux USB kernel compatibility layer.

- New UGEN backend and libusb library, finally solves the "driver
unloading" problem. The new BSD licensed libusb20 library is fully
compatible with libusb-0.1.12 from sourceforge.

- New "usbconfig" utility, for easy configuration of USB.

- Full support for Split transactions, which means you can use your
full speed USB audio device on a high speed USB HUB.

- Full support for HS ISOC transactions, which makes writing drivers
for various HS webcams possible, for example.

- Full support for USB on embedded platforms, mostly cache flushing
and buffer invalidating stuff.

- Safer parsing of USB descriptors.

- Autodetect of annoying USB install disks.

- Support for USB device side mode, also called USB gadget mode,
using the same API like the USB host side. In other words the new
USB stack is symmetric with regard to host and device side.

- Support for USB transfers like I/O vectors, means more throughput
and less interrupts.

- ... see the FreeBSD quarterly status reports under "USB project"

2) To enable the driver in the default kernel build:

2.a) Remove all existing USB device options from your kernel config
file.

2.b) Add the following USB device options to your kernel configuration
file:

# USB core support
device usb2_core

# USB controller support
device usb2_controller
device usb2_controller_ehci
device usb2_controller_ohci
device usb2_controller_uhci

# USB mass storage support
device usb2_storage
device usb2_storage_mass

# USB ethernet support, requires miibus
device usb2_ethernet
device usb2_ethernet_aue
device usb2_ethernet_axe
device usb2_ethernet_cdce
device usb2_ethernet_cue
device usb2_ethernet_kue
device usb2_ethernet_rue
device usb2_ethernet_dav

# USB wireless LAN support
device usb2_wlan
device usb2_wlan_rum
device usb2_wlan_ral
device usb2_wlan_zyd

# USB serial device support
device usb2_serial
device usb2_serial_ark
device usb2_serial_bsa
device usb2_serial_bser
device usb2_serial_chcom
device usb2_serial_cycom
device usb2_serial_foma
device usb2_serial_ftdi
device usb2_serial_gensa
device usb2_serial_ipaq
device usb2_serial_lpt
device usb2_serial_mct
device usb2_serial_modem
device usb2_serial_moscom
device usb2_serial_plcom
device usb2_serial_visor
device usb2_serial_vscom

# USB bluetooth support
device usb2_bluetooth
device usb2_bluetooth_ng

# USB input device support
device usb2_input
device usb2_input_hid
device usb2_input_kbd
device usb2_input_ms

# USB sound and MIDI device support
device usb2_sound

2) To enable the driver at runtime:

2.a) Unload all existing USB modules. If USB is compiled into the
kernel then you might have to build a new kernel.

2.b) Load the "usb2_xxx.ko" modules under /boot/kernel having the same
base name like the kernel device option.
