sfc: Wait for the link to stay up before running loopback selftest
It's been observed that some phys (such as the qt2025c) can
do down-up-down-up transitions, presumably as pcs block lock
settles down.
The loopback selftest will start sending data immediately
after the link comes up. Work around this by waiting for
the link state to stay up for two consecutive polls, rather
than one.

sfc: Workaround flush failures on Falcon B0
Under certain conditions a PHY may backpressure Falcon B0
in such a way that flushes timeout. In normal circumstances
the phy poller would fix the PHY, and the flush could complete.
But efx_nic_flush_queues() is always called after efx_stop_all(),
so the poller has been stopped. Even if this weren't the case,
how long would we have to wait for the poller to fix this? And
several callers of efx_nic_flush_queues() are about to reset
the device anyway - so we don't need to do anything.
Work around this bug by scheduling a reset. Ensure that the
MAC is never rewired back into the datapath before the reset
runs (we already ignore all rx events anyway).

Currently such notifications are only generated when the device comes up or the
address changes. However one use case for these notifications is to enable
faster network recovery after a virtual machine migration (by causing switches
to relearn their MAC tables). A migration appears to the network stack as a
temporary loss of carrier and therefore does not trigger either of the current
conditions. Rather than adding carrier up as a trigger (which can cause issues
when interfaces a flapping) simply add an interface which the driver can use
to explicitly trigger the notification.

ALSA: snd-usb-caiaq: Restore 'Control vinyl' input mode on A4DJ
This feature was undocumented on early A4DJ units. It is indicated
by lighting both the 'line' and 'phono' lamps at the same time.
Newer units document this and the newer Windows drivers enable this
for all units, so restore the functionality.
This patch simplifies the code and changes the mode mapping to match
the A8DJ, favouring simpler code and consistency over keeping the
existing mapping.
Both 'Control vinyl' and 'Phono' input modes enable the hardware
preamp. The difference is the input impedance.

ALSA: hda: Use LPIB for a Shuttle device
BugLink: https://launchpad.net/bugs/551949
Symptom: On the reporter's Shuttle device, using PulseAudio in Ubuntu
10.04 LTS results in "popping clicking" audio with the PA crashing
shortly thereafter.
Test case: Using Ubuntu 10.04 LTS (Linux 2.6.32.12), Linux 2.6.33, or
Linux 2.6.34, adjust the HDA device's volume with PulseAudio.
Resolution: add SSID for this machine to the position_fix quirk table,
explicitly specifying the LPIB method.

use the _killable wait_for_completion variants to abort on SIGKILL but

fs_enet: Adjust BDs after tx error
This patch fixes an occasional transmit lockup in the mac-fcc which
occurs after a tx error. The test scenario had the local port set
to autoneg and the other end fixed at 100FD, resulting in a large
number of late collisions.
According to the MPC8280RM 30.10.1.3 (also 8272RM 29.10.1.3), after
a tx error occurs, TBPTR may sometimes point beyond BDs still marked
as ready. This patch walks back through the BDs and points TBPTR to
the earliest one marked as ready.
Tested on a custom board with a MPC8280.
