From bdbfd6b582f55384059d9ac5e65b3653092e6adf Mon Sep 17 00:00:00 2001 From: Sujith Manoharan Date: Wed, 27 Apr 2011 16:56:51 +0530 Subject: mac80211: Add new API for rate selection This patch adds a new API for setting a TX rate mask in drivers that have rate control in either the firmware or hardware. This can be used for various purposes, for example, masking out the 11b rates in P2P operation. Signed-off-by: Sujith Manoharan Signed-off-by: John W.
