From 60ae0f20058d19ada94093dc3ef7ae0737597fba Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Tue, 10 Aug 2010 09:46:39 +0200 Subject: [PATCH] mac80211: move key tfm setup There's no need to keep separate if statements for setting up the CCMP/AES-CMAC tfm structs; move that into the existing switch statement.
