Kevin Lo e1b74f21f5 Add initial support for RTL8152 USB Fast Ethernet. RTL8152 supports
IPv4/IPv6 checksum offloading and VLAN tag insertion/stripping.

Since uether doesn't provide a way to announce driver specific offload
capabilities to upper stack, checksum offloading support needs more work
and will be done in the future.

Special thanks to Hayes Wang from RealTek who gave input.
