These two flags are used for the same purpose, just
combine them into a no-ir flag to annotate no initiating
radiation is allowed.
Old userspace sending either flag will have it treated as
the no-ir flag. To be considerate to older userspace we
also send both the no-ir flag and the old no-ibss flags.
Newer userspace will have to be aware of older kernels.

We must do this before interrupts are disabled since we rely on an

mac80211 currently sets WIPHY_FLAG_SUPPORTS_SCHED_SCAN based on whether

be correct for all drivers, we're adding scheduled scan to the iwlmvm
driver but it depends on firmware support.
Therefore, move setting WIPHY_FLAG_SUPPORTS_SCHED_SCAN into the drivers
so that they can control it regardless of implementing the operation.
This currently only affects the TI drivers since they're the only ones
implementing scheduled scan (in a mac80211 driver.)

The fw_status wasn't zeroed during allocation, resulting
in uninitialized var usage, and finally causing AP
traffic stop after recovery.
The wrong value in fw_status_2->counters.tx_lnk_free_pkts
led to a bad lnk->allocated_pkts calculation in
wlcore_fw_status(), causing wl18xx_lnk_low_prio() to return
FALSE (lnk->allocated_pkts > thold).
This eventually blocked the link in wlcore_tx_work_locked(),
as wl1271_skb_dequeue() continuously returned NULL.
Fix it by zeroing wl->fw_status_1/2 during allocation.

Accumulate the total number of sent packets per-link to find out how far
the encryption sequence number has progressed. Use this number as the
initial security sequence number after recovery.
This consolidates security sequence handling for both chip families, as
we no longer have to rely on 12xx specific Tx completion.
A fortunate side effect of this is correct management of seq numbers for
AP roles and multi-role scenarios.
When a link is removed we save the last seq number on a persistent part
of the wlvif. This helps the data survive through recoveries/suspends,
which also entail changes in the hlid of the link.
This functionality is STA only currently.

When TX aggregation is stopped, there are a few
different cases:
- connection with the peer was dropped
- session stop was requested locally
- session stop was requested by the peer
- connection was dropped while a session is stopping
The behaviour in these cases should be different, if
the connection is dropped then the driver should drop
all frames, otherwise the frames may continue to be
transmitted, aggregated in the case of a locally
requested session stop or unaggregated in the case of
the peer requesting session stop.
Split these different cases so that the driver can
act accordingly; however, treat local and remote stop
the same way and ask the driver to not send frames as
aggregated packets any more.
In the case of connection drop, the stop callback the
driver is otherwise supposed to call is no longer
required.
