iwlwifi: enable packet injection for iwlagn
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 <netrolller.3d@gmail.com> Signed-off-by: Zhu Yi <yi.zhu@intel.com> Signed-off-by: John W.
