Looks like this breaks kunit:

ok 70 mac80211-tpe
    KTAP version 1
    # Subtest: mac80211-mlme-chan-mode
    # module: mac80211_tests
    1..1
        KTAP version 1
        # Subtest: test_determine_chan_mode
        ok 1 Normal case, EHT is working
        ok 2 Requiring EHT support is fine
        ok 3 Lowering the mode limits us
kunit: required basic rate or BSS membership selectors not supported or disabled, rejecting connection
        ok 4 Requesting a basic rate/selector that we do not support
        ok 5 As before, but userspace says it is taking care of it
