Yeah I would've just manually commented out the SEQNO_OFFLOAD line. :-)

ok, the locking looks ok. I'm looking at the iwlwifi driver and it does
seem to have situations
where it /does/ assign a sequence number from the linux wireless stack, but
I'm not sure
whether it's used in the more recent chipsets.

I'll tinker a bit, and I've asked the linux iwlwifi maintainer if the
firmware needs
sequence numbers from the driver for anything.
