Subject: [PATCH 23/65] staging: wfx: drop wvif->enable_beacon

From: Jérôme Pouiller <jerome.pouiller@...abs.com>

It seems that current code try to save calls to hif_beacon_transmit() by
keeping a copy of the previous value of bss_conf->enable_beacon.
However, hif_beacon_transmit() does not cost so much and mac80211
already take care to not send useless events.
