From b3a47ee0ec07b16f68c38052e8cd1b5cb417bdca Mon Sep 17 00:00:00 2001 From: Arik Nemtsov Date: Thu, 10 May 2012 12:13:33 +0300 Subject: [PATCH] wlcore: support peer MIMO rates Parse the peer ht_cap element containing MCS8-MCS15 rates and pass it to the FW. Rates unsupported by the HW will be sanitized by mac80211 before reaching us.
