[PATCH 5.19 0475/1157] wifi: mac80211: move some future per-link data to bss_conf

Greg Kroah-Hartman
2022-08-15T23:54:57Z

From: Johannes Berg <johannes.berg@intel.com>

[ Upstream commit d0a9123ef548def5c8880e83e5df948eb5b55c62 ]

To add MLD, reuse the bss_conf structure later for per-link
information, so move some things into it that are per link.

Most transformations were done with the following spatch:

@@
expression sdata;
identifier var = { chanctx_conf, mu_mimo_owner, csa_active, color_change_active, color_change_color };
@@
-sdata->vif.var
+sdata->vif.bss_conf.var

@@
struct ieee80211_vif *vif;
identifier var = { chanctx_conf, mu_mimo_owner, csa_active, color_change_active, color_change_color };
@@
-vif->var
+vif->bss_conf.var
