Registering the card as a wakeup source needs to
be done once, during initialization. When the WOW
configuration changes, the card's status as wakeup
source needs to be changed too and this is done
via the set_wakeup() callback. Also, make sure
the device is removed properly using ath9k_deinit_wow().

When AP is started, firmware exits power save mode. This
means power save manager of AP takes priority over station.
Firmware stop sending periodic AWAKE events to host.
We may have UAPSD enabled on station which buffers data
packets until AWAKE event from firmware. Data path is
unnecessarily blocked in this case. This patch disables
UAPSD mode to reenable transmit data path.

After commit e9d8b2c2968499c1f96563e6522c56958d5a1d0d (xen-netback:
disable rogue vif in kthread context), a fatal (protocol) error would
leave the guest Rx thread spinning, wasting CPU time. Commit
ecf08d2dbb96d5a4b4bcc53a39e8d29cc8fef02e (xen-netback: reintroduce
guest Rx stall detection) made this even worse by removing a
cond_resched() from this path.
Since a fatal error is non-recoverable, just allow the guest Rx thread
to exit. This requires taking additional refs to the task so the
thread exiting early is handled safely.

80 VFs
Commit de966c592802 (net/mlx4_core: Support more than 64 VFs) was meant to
allow up to 126 VFs. However, due to leaving MLX4_MFUNC_MAX too low, using
more than 80 VFs resulted in memory corruptions (and Oopses) when more than
80 VFs were requested. In addition, the number of slaves was left too high.
This commit fixes these issues.

Currently qlge_update_hw_vlan_features() will always first put the
interface down, then update features and then bring it up again. But it
is possible to hit this code while the adapter is down and this causes a
non-paired call to napi_disable(), which will get stuck.
This patch fixes it by skipping these down/up actions if the interface
is already down.
