From d10c4ec8b4bc02f3874c7ef3c3539e4e7e123969 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Stefanik=20G=C3=A1bor?= Date: Wed, 3 Sep 2008 11:26:59 +0800 Subject: [PATCH] iwlwifi: enable packet injection for iwlagn MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Handle station IDs of transmitted packets when in monitor mode, and remove the various anti-injection checks from the iwl4965 driver. This makes injection work on iwl4965 and iwl5000. Tested on both cards. Note: To inject management frames with encryption, HW crypto support must be disabled using the "swcrypto=1" modparam (or "swcrypto50=1" for iwl5000). Otherwise most management frames won't be transmitted. Signed-off-by: Gábor Stefanik Signed-off-by: Zhu Yi Signed-off-by: John W.
