With bi-directional stress traffic, the receiver could hang causing the
hardware to stop and a "Detected Tx Unit Hang" message dumped to the system
logfile. Temporarily workaround this issue by disabling Tx flow control by
default. The issue is currently being investigated and a follow-on patch
will be provided to revert this when it is resolved.
