Add VLAN hardware tag insertion/stripping support. Tx/Rx checksum
offload for VLAN frames are also supported. The VLAN hardware
assistance is available only on 82550/82551 based controllers.
While I'm here change the confusing name of bit1 in byte 22 of
configuration block to vlan_drop_en. The bit controls whether
hardware strips VLAN tagged frame or not. Special thanks to wpaul
who sent valuable VLAN related information to me.
Tested on: i386, sparc64
