From f1871abd27641c020298b5c7654e1d8341f22e5f Mon Sep 17 00:00:00 2001 From: Ilan Peer Date: Thu, 8 Jun 2023 16:36:08 +0300 Subject: wifi: mac80211: Add getter functions for vif MLD state As a preparation to support disabled/dormant links, add the following function: - ieee80211_vif_usable_links(): returns the bitmap of the links that can be activated. Use this function in all the places that the bitmap of the usable links is needed. - ieee80211_vif_is_mld(): returns true iff the vif is an MLD. Use this function in all the places where an indication that the connection is a MLD is needed.
