Thanks. One clarification regarding the proposed removal: sta_set_sinfo() is common to
both AP and STA interfaces, and NL80211_STA_INFO_BSS_PARAM is also reported for the STA-side
station dump, where these parameters describe the BSS the station is associated with.

Would it be reasonable to remove NL80211_STA_INFO_BSS_PARAM only from the AP-side station
information, including AP_VLAN, while retaining it for the STA side?

If so, I can simplify the change accordingly and avoid adding the AP_VLAN-specific
BSS configuration lookup.
