From ddf5c2bd1044d923ad82f519c68cdf12a055a568 Mon Sep 17 00:00:00 2001 From: Jes Sorensen Date: Thu, 19 Jun 2014 11:37:24 +0200 Subject: [PATCH] staging: rtl8723au: Update bss beacon info in rtw_add_beacon() Pull out the core info beacon_interval, capability, and tsf and update cur_network.network with the info in rtw_add_beacon() instead of relying on it being in ->IEs. This will help later when getting rid of the beacon struct info from ->IEs and only carrying the actual IEs there.
