From 35afa588624c4f9e19a0edfbb51769b59c90bb0d Mon Sep 17 00:00:00 2001 From: Helmut Schaa Date: Wed, 9 Sep 2015 09:46:32 +0200 Subject: mac80211: Copy tx'ed beacons to monitor mode When debugging wireless powersave issues on the AP side it's quite helpful to see our own beacons that are transmitted by the hardware/driver. However, this is not that easy since beacons don't pass through the regular TX queues. Preferably drivers would call ieee80211_tx_status also for tx'ed beacons but that's not always possible. Hence, just send a copy of each beacon generated by ieee80211_beacon_get_tim to monitor devices when they are getting fetched by the driver. Also add a HW flag IEEE80211_HW_BEACON_TX_STATUS that can be used by drivers to indicate that they report TX status for beacons.
