From ffa9598ecb93630a45564b95ae17362b819b38de Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Fri, 2 Sep 2022 16:12:43 +0200 Subject: wifi: mac80211: add ieee80211_find_sta_by_link_addrs API Add a new API function ieee80211_find_sta_by_link_addrs() that looks up the STA and link ID based on interface and station link addresses. We're going to use it for mac80211-hwsim to track on the AP side which links are active.
