Not using the lowest rate is intentional. Using the lowest rate severely
limits aggregation. In many cases, dropping a packet is preferrable, as
trying too hard to retry individual packets can cause extra bufferbloat
and severely increased latencies.

NACK from me on this patch. If anything, I think we should probably
change minstrel to behave in the same way as minstrel_ht.
