Subject: [PATCH] mac80211: report assoc_link_id in station info for non-MLD
STAs on MLD AP
When a non-MLD station associates with an MLD AP, it does so on a
specific link. However, sta_set_sinfo() never sets mlo_params_valid,
so nl80211 never emits NL80211_ATTR_MLO_LINK_ID in get_station /
dump_station responses. Userspace has no way to determine which link
a non-MLD STA is associated on.
Set mlo_params_valid to 1 and assoc_link_id to sta->deflink.link_id,
when valid_links is set.
Also set the mld_addr copy only for MLD STAs, so that non-MLD STAs
get a zeroed mld_addr as documented.
