Comment (by [EMAIL PROTECTED]):
I have a general doubt regarding power ssenario here. AP has added data
packets for Station A in Hardware Queue (not transmitted in Air).
How will we handle the case when the same station goes into Power Save
mode
(before its packet are actually transmitted in air). Is there any way to
check
station's Power Save mode just before throwing the packet in Air. Or these
packets
are dropped??
In present madwifi implementation we check Station's Power Save mode in
hardstart function
in ieee80211.c file. If PS Mode is enabled then it is queued o.w. given to
parent_queue_xmit
function in if_ath.c file. What if station changes its Power Save mode in
between i.e., after
packet is given to parent_queue_xmit but before actually sent in Air.
