From a3caa99e6c68f466c13cfea74097f6fb01b45e25 Mon Sep 17 00:00:00 2001 From: "John W. Linville" Date: Tue, 25 Aug 2009 14:12:25 -0400 Subject: libipw: initiate cfg80211 API conversion (v2) Initiate the conversion of libipw to the new cfg80211 configuration API. For now, leave CONFIG_IPW2200_PROMISCUOUS stuff alone. Eventually migrate it to cfg80211 when the add/del/change_virtual_intf methods are implemented. (v2: Fix unconditional wiphy_unregister in libipw which was causing problems for ipw2100, somewhat based on prior attempted fix by Zhu Yi . Previously both original version of this patch and Zhu Yi's fix attempt were reverted due to discovery of regressions. -- JWL) Signed-off-by: John W.
