Dave,

Here is another handful of late-breaking fixes intended for the 3.8
stream...  Hopefully the will still make it! :-)

There are three mac80211 fixes pulled from Johannes:

"Here are three fixes still for the 3.8 stream, the fix from Cong Ding
for the bad sizeof (Stephen Hemminger had pointed it out before but I'd
promptly forgotten), a mac80211 managed-mode channel context usage fix
where a downgrade would never stop until reaching non-HT and a bug in
the channel determination that could cause invalid channels like HT40+
on channel 11 to be used."

Also included is a mwl8k fix that avoids an oops when using mwl8k
devices that only support the 5 GHz band.

Please let me know if there are problems!

John
