Disable hardware checksum offloading of IP fragments in the bge
driver. I tried a few obvious experiments, but was unable to make
the 3c996B-T generate correct UDP checksums for transmitted fragmented
packets. I'm not so sure the device is even capable of it.
This fixes NFS over UDP.

Looks like the problem is with receiving fragmented UDP packet. In chip
documentation it is said, that it will not calculated checksum for
fragmented UDP packet, however from the context it looks like this
is related only to transmitting.
