Modified Files:
        src/sys/dev/pci: if_vge.c

Log Message:
Fix hardware VLAN tagging support on vge(4):

- On TX, vge(4) seems to assume that tags are written in little endian.
  We already use htole32() to write values into descriptors,
  so extra byteswap by htons() is not needed there.

- On RX, vge(4) seems to store tags in network byteorder.
  We have to swap byteorder regardless of host's byteorder
  (i.e. we have to use bswap16() rather than ntohs())
  because we already use le32toh() to read values from descriptors.

Anyway, no need to use htons()/ntohs() because there is no stream data.

Tested on both i386 and macppc, and OK'ed by Pavel Cahyna.
