IE's are parsed from beacon buffer and stored locally using

Sometimes the local pointers point to the data inside IE, but

Sometimes, due to the race between Rx path and WMI_BA_STATUS_EVENTID WMI event,
few frames may be passed to the stack before reorder buffer allocated.
Then, after BACK establishment, it start getting frames with sequence number ahead of
SSN, and it get interpreted as missing frames. Then, BACK mechanism will wait
for missing frames; data traffic will be stopped. In case of interface configured
for DHCP, this data delay causes DHCP failure.
Relax checking for sequence number; use sequence of 1-st frame handled by the buffer
as SSN for this buffer.
This is work-around, real fix should be done when proper BACK mechanism implemented.

HW should never attempt to perform DMA for unused queues.
For rtl8187se this is ensured by setting a dedicated register at
init time, before enabling TX.
In rtl8180/5 the register is only written at the first TX (because
in rtl8180/5 it serves also to kick DMA for used queues).
This should be enough, but it's worth to add a register write at
init time, before enabling TX.

This allows processing of the last regulatory request when
we determine its still pending. Without this if a regulatory
request failed to get processed by userspace we wouldn't
be able to re-process it later. An example situation that can
lead to an unprocessed last_request is enabling cfg80211 to
be built-in to the kernel, not enabling CFG80211_INTERNAL_REGDB
and the CRDA binary not being available at the time the udev
rule that kicks of CRDA triggers.
In such a situation we want to let some cfg80211 triggers
eventually kick CRDA for us again. Without this if the first
cycle attempt to kick off CRDA failed we'd be stuck without
the ability to change process any further regulatory domains.
cfg80211 will trigger re-processing of the regulatory queue
whenever schedule_work(®_work) is called, currently this
happens when:
* suspend / resume
* disconnect
* a beacon hint gets triggered (non DFS 5 GHz AP found)
* a regulatory request gets added to the queue
We don't have any specific opportunistic late boot triggers
to address a late mount of where CRDA resides though, adding
that should be done separately through another patch.
Without an opportunistic fix then this fix relies at least
one of the triggeres above to happen.

In addition we need to knock the VF offline so that it does not continue
