From b6a27d1e6b8e163dee054c9cd03639c62756c2e2 Mon Sep 17 00:00:00 2001 From: Nikolay Martynov Date: Thu, 8 Dec 2011 21:43:39 -0500 Subject: [PATCH] iwlwifi regression in 20111205 merge It looks like the regression was introduced between 20111202 and 20111205 (linux-next tree). Symptoms: connection to AP seem to be established, but no data goes though it in any way. Tested on intel 5300. Peek at the changes have shown that it looks like at least part of the code wasn't merged properly. It was originally committed into iwl_agn.c but code in question was moved to iwl-mac80211.c. This patch puts code in place and my card works again. Signed-off-by: Nikolay Martynov Signed-off-by: John W.
