[PATCH 0/4] Improve queue handling for off-channel operation

[Seth Forshee <seth.forshee@canonical.com>]

Hi Johannes,

Here are some updates to the tx queue handling patches during
off-channel operation that were part of the larger series I sent last
week. I didn't see any reason to sit on these while I finished
implementing the powersave changes. This includes the patches to return
a status from tx operations, add an off-channel queue stop reason, and
improve error handling when going off-channel.

Changes since v1:
 * Add unlikely() to the off-channel condition in ieee80211_tx_frags()
 * Expand the queue stop reasons that will cause off-channel frames to
   be dropped to include everything except the off-channel stop reason
 * Remove changes to abort scans when sending of probe request frames
   failed

Thanks,
Seth
