Upon investigation, it looks like the VT6105M isn't actually using the 
hardware checksum offloading support of the hardware.  Are there any 
known reasons why this isn't enabled (hardware bugs?)?  I'll test enabling 

As far as I can tell it was never attempted.  So it should work.

If you do that, while you're here, you can make rhine_rx() take
a "napi" arg and make this driver use netif_gso_receive() too.
Don't forget to set NETIF_F_GRO or similar in netdev->flags during
probe, and also hookup the necessary ethtool hooks.

I have a patch to enable hw checksumming (the ethtool hooks are done, but I
somehow missed the NETIF_F_GRO bit). Care to give it a whirl?
