From 319090bf6c75e3ad42a8c74973be5e78ae4f948f Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Mon, 17 Nov 2014 14:08:11 +0100 Subject: cfg80211: remove enum station_info_flags This is really just duplicating the list of information that's already available in the nl80211 attribute, so remove the list. Two small changes are needed: * remove STATION_INFO_ASSOC_REQ_IES complete, but the length (assoc_req_ies_len) can be used instead * add NL80211_STA_INFO_RX_DROP_MISC which exists internally but not in nl80211 yet This gets rid of the duplicate maintenance of the two lists.
