====================
sunvnet: add SG, HW_CSUM, GSO, and TSO support

This patch set adds everything needed for TSO support in sunvnet. On my
test hardware, this increases the single-stream TCP throughput for the
default 1500-byte MTU Linux-Linux from ~2Gbps to 10Gbps and Linux-Solaris
from ~2Gbps to 6Gbps.
