From 922368414e5700d1ed51510e54137359297d78e7 Mon Sep 17 00:00:00 2001 From: =?utf8?q?G=C3=A1bor=20Stefanik?= Date: Thu, 23 Apr 2009 20:06:06 +0200 Subject: [PATCH] mac80211: Fix handling of retry count of NO_ACK frames in PID MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Make PID check for IEEE80211_TX_CTL_NO_ACK instead of is_multicast_ether_addr when determining whether to use the lowest rate, and set the retry count to 0 (total try count = 1) if IEEE80211_TX_CTL_NO_ACK is set.
