From f68d776a04bfcebc426f605c4440ffe38c583a4b Mon Sep 17 00:00:00 2001 From: Thomas Pedersen Date: Wed, 23 Jan 2013 12:18:13 -0800 Subject: [PATCH] mac80211: support mesh rate updates An existing mesh station entry may change its rate capabilities, so call rate_control_rate_update() to notify the rate control.
