From ea559b460509b241cc1a3f36eebe0b2b634b3cf2 Mon Sep 17 00:00:00 2001 From: Guy Eilam Date: Thu, 9 Dec 2010 16:54:59 +0200 Subject: [PATCH] wl1271: fixed problem with WPS IEs in probe requests Inclusion of a WPS IE in probe requests caused a problem in the driver due to the maximum size of the probe request template and the max_scan_ie_len values at initialization. Increased the size of probe request template to the maximum size allowed by the firmware. Struct wl12xx_probe_req_template, which was only used for calculating the max size of the probe request template, is no longer used and needed. max_scan_ie_len is used for validating the size of additional IEs in scan requests. Initialized the max_scan_ie_len field to the maximum size of the probe request template minus the ieee80211 header size.
