Subject: [PATCH 092/146] iwlwifi: mvm: support TX on MONITOR iface
Git-commit: 6d759b02f4121595bf4212662e73c26573dab61a
Patch-mainline: v4.13-rc1
References: FATE#322675

When trying to TX through a monitor interface, the
conditions in iwl_mvm_tx_skb_non_sta() don't match
and the frame tries to go out from an usued TXQ.

Add a check for monitor iface, and use the AUX queue
in such a case.

In non-DQA mode the frame is sent through the
static-allocated queues anyway, so the problem is
in DQA mode only.
