From 93b05238027420978d785569f8c1aa4a6867bc13 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Tue, 28 Sep 2010 12:53:14 +0200 Subject: cfg80211: always set IBSS basic rates IBSS started from wireless extensions is currently missing basic rate configuration, fix this by moving the code to generate the default to the common code that gets invoked for both nl80211 and wext.
