From: Johannes Berg Date: Wed, 23 Dec 2009 12:15:34 +0000 (+0100) Subject: mac80211: generalise management work a bit X-Git-Tag: v3.12-rc1~11246^2~49^2~413 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f679f65d417c3ea3f91b4bbfb68e3951c9eb8f04;p=kernel%2Fkernel-generic.git mac80211: generalise management work a bit As a first step of generalising management work, this renames a few things and puts more information directly into the struct so that auth/assoc need not access the BSS pointer as often -- in fact it can be removed from auth completely. Also since the previous patch made sure a new work item is used for association, we can make the different data a union. Signed-off-by: Johannes Berg Signed-off-by: John W.
