Add device driver support for the VIA Networking Technologies VT6122 gigabit ethernet chip and integrated 10/100/1000 copper PHY. The vge driver has been added to GENERIC for i386, pc98 and amd64, but not to sparc or ia64 since I don't have the ability to test it there. The vge(4) driver supports VLANs, checksum offload and jumbo frames. Also added the lge(4) and nge(4) drivers to GENERIC for i386 and pc98 since I was in the neighborhood. There's no reason to leave them out anymore.
