From 4edf040afc9237aa8cc90bcf54b521ac47d1ed78 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?G=C3=A1bor=20Stefanik?= Date: Thu, 23 Apr 2009 19:36:00 +0200 Subject: mac80211: Fix handling of retry count of NO_ACK frames in minstrel MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Make the retry count zero (total try count = 1) for frames with IEEE80211_TX_CTL_NO_ACK set. Also remove the check for is_multicast_ether_addr in use_low_rate, which is redundant because all multicasts have IEEE80211_TX_CTL_NO_ACK set. Signed-off-by: Gábor Stefanik Signed-off-by: John W.
