mac80211 already filled in the MCS rate info for rx'ed frames but tx'ed
frames that are sent to a monitor interface during the status callback
lack this information.

Add the radiotap fields for MCS info to ieee80211_tx_status_rtap_hdr
and populate them when sending tx'ed frames to the monitors.

The needed headroom is only extended by one byte since we don't include
legacy rate information in the rtap header for HT frames.

Get rid of the ieee80211_tx_status_rtap_hdr struct and instead build the
rtap header dynamically. This makes it easier to extend the rtap header
generation in the future.

Add ieee80211_tx_radiotap_len to calculate the expected size of the
rtap header before generating it. Since we can't check if the rtap
header fits into the requested headroom during compile time anymore
add a WARN_ON_ONCE.

Also move the actual rtap header generation into its own function.

While inspecting the code, I saw that iwl_tx_queue_unmap modifies
the read pointer of the Tx queue without taking any locks. This means
that it can race with the reclaim flow. This can possibly lead to
a DMA warning complaining that we unmap the same buffer twice.

This is more a W/A than a fix since it is really weird to take
sta_lock inside iwl_tx_queue_unmap, but it can help until we revamp
the locking model in the transport layer.

Occasionally, the device will send interrupts
while it is resuming, at a point where we are
not set up again to handle them. This causes
the core IRQ handling to completely disable
the IRQ, and then the driver won't work again
until it is reloaded/rebound.

To fix this issue disable the IRQ on suspend,
this will cause us to only get interrupts
again after we've setup everything on resume.

802.11 says:
"Sequence numbers for QoS (+)Null frames may be

However, if we use the normal counters then peers
will get confused with aggregation since there'll

QoS Null frames.

Updating the beacon every time right after one was
transmitted is pointless, most of the time we might
not even have to update it. We will update it every
time it changes, which includes from set_tim(), a
callback iwlwifi didn't implement so far.

This also reduces latency for clients, previously
we would update the beacon right after the previous
one was transmitted, and then a TIM change would
only take effect after that again -- updating the
beacon right after the TIM changes makes the TIM
change go out to the air faster.
