From cb71f1d136a635decf43c3b502ee34fb05640fcd Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Tue, 31 May 2022 23:20:08 +0200 Subject: wifi: mac80211: add sta link addition/removal Add the necessary infrastructure, including a new driver method, to add/remove links to/from a station. To do this, refactor the link alloc/free a bit, splitting that so we can do it without linking them, to handle failures better. Note that a station entry must be created representing an MLD or a non-MLD STA, it cannot change between the two. When representing an MLD, the 'deflink' is used for the first link, which might be removed later, in which case the memory isn't reused.
