From 89888e368eebb8d5c3dbf58425b95fc773aee511 Mon Sep 17 00:00:00 2001 From: Lorenzo Bianconi Date: Sat, 24 Sep 2011 18:48:26 +0200 Subject: mac80211: max_tp_rate2 management of minstrel_ht I noticed a possible issue in the max_tp_rate2 management of minstrel_ht. In particular, if we look up just among max_tp_rate2 of each group it will be possible that the selected rate will not be the mcs with second maximum throughput. I wrote this simple patch.
