From 197a4e4e1f7ef11458f09b4dd74397baf6758133 Mon Sep 17 00:00:00 2001 From: Yogesh Ashok Powar Date: Wed, 1 Feb 2012 16:19:54 +0530 Subject: [PATCH] mwl8k: Remove BSSID from the firmware when the BSS is stopped Using command DEL_MAC_ADDR, remove the mac address of the BSS when it is stopped i.e the corresponding vif is removed. Without this, the stale bss entry will still be maintained in the firmware which causes issues when the BSS's are recreated.
