Subject: [wireless] update ieee80211 to 2.6.25
Message-id: 20080813163353.GC18695@redhat.com
O-Subject: [RHEL5 patch 1/3] Update ieee80211 component to match version from 2.6.25
Bugzilla: 448762
This patch updates ieee80211 and its accompanying softmac component
to match what was current in 2.6.25.
BZ448762
Tested against the related drivers by me with good results.
