Since the commit below, iwldvm sends the FLUSH command to
the firmware. All the devices that use iwldvm have a
firmware that expects the _v3 version of this command,
besides 5150.
5150's latest available firmware still expects a _v2 version
of the FLUSH command.
This means that since the commit below, we had a mismatch for
this specific device only.
This mismatch led to the NMI below:

In 8000 B-step the FW file has changed, but by the time we
know the HW step, the FW file is already requested.

This patch defaults 8000 family to B-step if no HW step is

really is (in 8000 family) and if it isn't B-step, the FW
file is released and the A-step file is requested.

When another vif is also running during a channel switch, we need to
use a session protection when we move to the new channel, so that we
don't miss the beacons.  Without this, sometimes the other vif
repeatedly gets time exactly when we should be hearing the beacons,
preventing channel switch from completing.  Adding a session
protection that lasts from the moment the channel changes until 2
TBTTs later, ensures that we will hear the beacons on the destination
channel.

After a channel switch, transmission on the new channel is only

We need to call ieee80211_chswitch_done() ourselves just when the
absence TE started, so we perform the actual context switch early
enough.  To do so, add a dummy channel_switch op, which will cause

ieee80211_chswitch_done() to complete the operation.

Now that mac80211 waits for the first beacon on the new channel before
