Really just poking around here...am I on the right track? Or is the
iwlagn firmware supposed to handle buffering broadcast frames?
Looking at Johannes's docs, I don't see anything that seems
to relate to "implement sequence numbering for frames with the
IEEE80211_TX_CTL_ASSIGN_SEQ flag (or ask the hardware to do it for
those frames)". Anyone know how to ask the hardware to do that?
I also don't see anything for "When sending probe response frames,
the timestamp must be adjusted by the hardware or firmware." But,
I didn't look too hard -- maybe I missed it?
