Commit 69c7fda40921c125eeeef6a827f6270ac6aa1baa removed the
users of iwl_mvm_tid_data.reduced_tpc. Due to a conflict,
I forgot to commit the hunk that removed the field itself.
Do this know.

Next hardware will direct TCP/UDP streams to different cores.
Packets belonging to the same stream will be directed to the same
core.
The result is that duplicates will be always directed to the same
rx queue were the first packet was received.
This enabled parallelizing the duplicate packet detection across
the different cores, without sharing data between the rx queues.

The 9000 hardware introduces the frame releaser, which
keeps track of the aggregation window and notifies host
of the window status. This requires in turn updating
the hardware with the RX BA session window size.
Firmware API was changed to enable that, update the driver
accordingly.

As we're working on multi-queue RX, we want to parallelise checking
the PN in order to avoid having to serialise the RX processing.
It may seem that doing parallel PN checking is insecure, but it turns
out to be OK because queue assignment is done based on the data in the
frame (IP/TCP) and thus cannot be manipulated by an attacker, since
the data is encrypted and must first have been decrypted successfully.
There are some corner cases, in particular when the peer starts using
fragmentation which redirects the packet to the default queue. However
this redirection is remembered (for the STA, per TID) and thus cannot
be exploited by an attacker either.
Leave checking on the default queue (queue 0) to mac80211, since we
get fragmented packets there and those are subject to stricter checks
during reassembly.

Currently when creating a new vif in monitor mode the driver doesn't
allocate a specific station. This causes that in the situation that
tx traffic is injected, the tx queues are not scheduled,
with the result of a TFD queue hang.
Fix that by allocating a station and ensuring its tx queues
are scheduled.

ilw@linux.intel.com is not available anymore.
linuxwifi@intel.com should be used instead.

When we have holes in the BA window, there might be frames
that have been ACKed between the read and the right
pointers. This means that these frames won't be scheduled
again by the SCD and the firwmare won't see them.
This invalidates the number of frames we tell the firmware
to send. When we detect this case, tell mac80211 to close
the SP and to send an EOSP so that the firmware can be in
sync.
