From f30221e4ec62d905b56d5e8f7ccab6b406a97cf5 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Thu, 25 Nov 2010 10:02:30 +0100 Subject: mac80211: implement off-channel mgmt TX This implements the new off-channel TX API in mac80211 with a new work item type. The operation doesn't add a new work item when we're on the right channel and there's no wait time so that for example p2p probe responses will be transmitted without delay.
