From e36cfdc9b17fa64245ee6206287e5120e59bbfca Mon Sep 17 00:00:00 2001 From: Jouni Malinen Date: Fri, 13 Jun 2008 19:44:48 +0300 Subject: [PATCH] mac80211_hwsim: Shared TX code for received frames and Beacons Use a shared function for transmitting the frames instead of duplicated code in two places.
