[ Upstream commit4073ea5161] Userspace may fail to connect to certain BSS that were initially marked as unusable due to regulatory restrictions (use_for = 0, e.g., 6 GHz power type mismatch). Even after these restrictions are removed and the BSS becomes usable, connection attempts still fail. The issue occurs in cfg80211_update_known_bss() where the use_for flag is updated using bitwise AND (&=) instead of direct assignment. Once a BSS is marked with use_for = 0, the AND operation masks out any subsequent non-zero values, permanently keeping the flag at 0. This causes __cfg80211_get_bss(), invoked by nl80211_assoc_bss(), to fail the check "(bss->pub.use_for & use_for) != use_for", thereby blocking association. Replace the bitwise AND operation with direct assignment so the use_for flag accurately reflects the current BSS state.
