Summary

Add support for sequence number offloading -

Check IEEE80211_CONF_SEQNO_OFFLOAD() before doing TX lock manipulation;
Don't call ieee80211_output_seqno_assign() if IEEE80211_CONF_SEQNO_OFFLOAD() is true.

TODO:

this doesn't yet do beacon sequence number allocation offloading; I'll tackle that later.

Note: my hope is to eventually delete the TX lock entirely; this sets the ground work to first experiment and test various drivers in this stack.

Ignoring the open question on the TODO this seems fine.

3863	When is this supposed to be done? Before or after this lands?

3863	after, because I am not yet sure if I have to split the two into different flags or not. Doing this work doesn't hurt anything, the beacon numbers will keep incrementing.
