This patch was adapted from 06f7bc7db7
(from linus's linux-2.6 tree of kernel.org)
here's the original message:
The queue stopping/waking functionality was broken in a way that could
cause huge latencies in TX transfers and even cause the TX to stall in the
right circumstances. Correct these problems.
