I checked this a bit further and I don't see the point in sending all
packets here.  In fact, if block_tx is set, we can't even send any more
frames until the switch happens (or fails).  So we should at least check
this here.

The block_tx is taken into account in the mac layer.

This is a bit strange, though.  I checked the code and nobody seems to
be using the block_tx element of ieee80211_channel_switch, so I wonder
why it's there at all.

As far as I know the block_tx is for the DFS channel switch 
implementation, when block_tx=1, the firmware will not start tx on new 
channel.

I'll check this up with our firmware team.
