net80211: convert the rest of the native net80211 drivers to SEQNO_OFFLOAD

[adrian]

Summary

• Convert the rest of the drivers to implement driver/offloaded sequence number handling.

• For drivers that implement their own sequence number space handling for A-MPDU, only call ieee80211_output_seqno_assign() if the frame isn't tagged with M_AMPDU_MPDU, which mirrors the original net80211 sequence number behaviour. (Except of course, the assignment is now happening during final encap/transmit, not early in encap.)

note: i haven't yet tested iwi, bwi, bwn - but i found the hardware, so i'll test it next week.
everything else has been tested.

Again; you know the drivers better; I was wondering about iwm; are we sure this is true for all cases?

sys/dev/iwm/if_iwm.c

Have you tested this? Is it true for all cases?

I do believe you would have to set it yourself but given there is no 11n support here... As-is is wrong. I would probably not set the flag? Or leave a comment at least?

I've tested it on all the iwm hardware i have here, it seems to work fine

[adrian]

oops, forgot to add iwn(4)

Testing I leave to you then; you know these devices and drivers better than I do. Scrolling through looked ok.
