net: lan78xx: Disable TCP Segmentation Offload (TSO)

TSO seems to be having issues when packets are dropped and the
remote end uses Selective Acknowledge (SACK) to denote that
data is missing. The missing data is never resent, so the
connection eventually stalls.

There is a module parameter of enable_tso added to allow
further debugging without forcing a rebuild of the kernel.
