My patch unfortunately does not solve the problem, as I can still see
the timeout error. However, by disabling flow control, the frequency
of the error is decreased to the point where it almost never happens
(even on devices where I would frequently see the error). In order to
deal with the remaining timeout cases, I wrote a small watchdog script
that checks syslog for the timeout message and restarts networking if
the error occurs. A restart has always been able to recover networking
(at the cost of a small interruption).
