[PATCH 13/19] staging: wfx: avoid duplicate updating of beacon template

From: Jerome Pouiller
Date: Fri Apr 10 2020 - 09:34:30 EST


From: JÃrÃme Pouiller <jerome.pouiller@xxxxxxxxxx>

When ERP changes, mac80211 call wfx_bss_info_changed() with
BSS_CHANGED_ERP_* and with BSS_CHANGED_BEACON.

The driver already update beacon template because of
BSS_CHANGED_BEACON. It is not necessary to also update beacon template
because of BSS_CHANGED_ERP_*.
