From fd821d1e8a8a4d21324c79c1d54b1131170c0721 Mon Sep 17 00:00:00 2001 From: Arend van Spriel Date: Tue, 8 Feb 2011 14:39:13 +0100 Subject: [PATCH] staging: brcm80211: implement mac80211 callback set_rts_threshold adds implementation for allowing configuration of dot11RTSThreshold as defined in the 802.11 standards. The mac80211 module will use callback set_rts_threshold to configure this in the driver.
