Hi Martin,
I replied original mail, because I think discussion would be clearer.

Is this because you have seen "failed to get tx report"?
Have you tried to increasing RTW_TX_PROBE_TIMEOUT?
If it still can't get TX report, we might take this workaround with comments
to mention why we need it. Or a local variable with proper naming to point out
this, like
bool queue_has_no_tx_report = queue > RTW_TX_QUEUE_VO;
By the way, USB behavior is very like to SDIO, but TX report seems to work well.

I think this change is reasonable, since skb via all kinds of queues could
set IEEE80211_TX_CTL_REQ_TX_STATUS.
