From d0be7cc7688d0cc2e4daf952c43b5ce86e5c8a1d Mon Sep 17 00:00:00 2001 From: Senthil Balasubramanian Date: Wed, 17 Sep 2008 12:39:49 +0530 Subject: ath9k: connectivity is lost after Group rekeying is done Connectivtiy is lost after Group rekeying is done. The keytype maintained by ath9k is reset when group key is updated. Though sc_keytype can be reset only for broadcast key the proper fix would be to use mac80211 provided key type from txinfo during xmit and get rid of sc_keytype from ath9k ath_softc.
