Remove bogus check for MT_PACKET_ID_NO_ACK in mt76_tx_status_skb_get, which is already handled in callers and turns timeout calls into no-ops Do not clean up pending status items on reordering of tx status information if the timeout is not reached yet Signed-off-by: -

mt76_init_stream_cap() and mt76_get_txpower() call __sw_hweight8() directly, but that's only defined if CONFIG_GENERIC_HWEIGHT is enabled. The function that works on all architectures is hweight8().
