Therefore it is not possible for the analyzer software to find the correct byte

It is relative common to get the data from a low end AP in big endian mode and
transfer it to another computer in little endian mode to analyze it. Therefore,
it would be better to store it in network (big endian) byte order.
The extension of the 8 bit bins for each bin to 16 bit is not necessary. This
operation can be done in userspace or on a different machine. Instead the
max_exp defining the amount of shifting required for each bin is exported to

mac80211: fix aggregation state with current drivers
For drivers that don't actually flush their queues when
aggregation stop with the IEEE80211_AMPDU_TX_STOP_FLUSH
or IEEE80211_AMPDU_TX_STOP_FLUSH_CONT reasons is done,
like iwlwifi or iwlegacy, mac80211 can then transmit on
a TID that the driver still considers busy. This happens
in the following way:
- IEEE80211_AMPDU_TX_STOP_FLUSH requested
- driver marks TID as emptying
- mac80211 removes tid_tx data, this can copy packets
to the TX pending queues and also let new packets
through to the driver
- driver gets unexpected TX as it wasn't completely
converted to the new API
Fortunately, solving this problem is easy as the station
is being destroyed, so such transmit packets can only
happen due to races. Instead of trying to close the race
just let the race not reach the drivers by making two
changes:
1) remove the explicit aggregation session teardown in
the managed mode code, the same thing will be done
when the station is removed, in __sta_info_destroy.
2) When aggregation stop with AGG_STOP_DESTROY_STA is
requested, leave the tid_tx data around as stopped.
It will be cleared and freed in cleanup_single_sta
later, but until then any racy packets will be put
onto the tid_tx pending queue instead of transmitted
which is fine since the station is being removed.
