Subject: Re: Please pull 'adm8211' branch of wireless-2.6

Come to think of it, this driver will depend on some of the mac80211
patches Dave M. has queued for net-2.6.24.  Perhaps it would be better
if Dave were to merge it with his tree?

Jeff, if you have no objection then please sign-off/ack/whatever so
davem can see it.  Dave, in that case please pull this to net-2.6.24.

Thanks!

John
