From 5f16a43617d46cf255a66f4dc193a7f5b2540aaf Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Fri, 25 Feb 2011 15:36:57 +0100 Subject: mac80211: support direct offchannel TX offload For devices supported by iwlwifi sometimes off-channel transmissions need to be handled by the device completely. To support this mac80211 needs to pass the frame directly to the driver and not through the TX path as the driver needs the frame and channel information at the same time.
