8139too has been tested on big-endian and little-endian, 32-bit and
64-bit processors without showing the behavior you're seeing.

If the packet is fine in rtl8139_start_xmit, it sounds like a hardware
problem. There is certainly the possibility that your platform is
interacting poorly in some way with the driver, but that's a slim
possibility. There's no way to know more without you doing some testing
and experimentation yourself.
