When the chip gets a transmit underrun, the driver resets the chip, which 

cause the link to go down for several seconds on my Dlink DFE580-TX (quad-port
DL1002). This behavior is unacceptable, especially as the driver usually
gets several underrun at once, causing the link to be almost unaviable
for several 10s of seconds.
Bump the default transmit threshold to 1504 bytes to avoid transmit underrun.
