From: Senthil Balasubramanian Date: Thu, 14 May 2009 13:12:08 +0000 (+0530) Subject: mac80211: Initialize RX's last received sequence number X-Git-Tag: v2.6.31-rc1~330^2~313^2~83 X-Git-Url: https://git.openpandora.org/cgi-bin/gitweb.cgi?p=pandora-kernel.git;a=commitdiff_plain;h=cccaec98a3ddbf20f22604f9ba405781c5f89f0e mac80211: Initialize RX's last received sequence number The STA may drop the very first frame if it happens to be a retried frame. This is because we maintian the last received sequence number per TID for QoS frames and it is initialized to zero through kzalloc during sta_info_alloc and the sequence number of the very first date frame received would be ZERO (as per IEEE 802.11-2007, 7.1.3.4.1). If the frame dropped happens to be an EAP Request Identity(very first frame from the AP), then wpa_supplicnat disconnects the STA and the whole procedure starts again.
