Because of exponential backoff, aggregated bandwidth of multiple TCP

However, RED like approach to attempt retries only a few times may be
a good strategy to improve latency.

A RED approach would be good, but in general there has to be a limit
on the queue. Your wireless interface should not become a packet long
term storage facility. I've seen RTTs to the base stations on the
order of 25000ms (that's 25 SECONDS) or more. If you can't deliver a
packet a through 300ns distance of air in 10ms, it is probably time to
drop it.
