 Modified Files:
 	src/sys/dev/pci: if_sip.c
 
 Log Message:
 VLAN tags were sent byte-swapped by the gsip driver, because the driver
 forgets to convert them from the host to the network byte order. Use
 bswap16 to convert them. (Not htons, because on a big-endian machine, they
 are in the correct byte order initially, but then, they are byte-swapped
 by a htole32 call when written to the transmit descriptor. So
 byte-swapping is needed in this case too, to compensate for this htole32
 call.)
 
 For a similar reason, tags were seen byte-swapped when received on a
 big-endian machine. Replace ntohs by bswap16 in the input path too.
 (Again, it is needed to compensate for a le32toh call when the receive
 descriptor is read.)
 
 Fixes PR 32644.
 
 Tested on 3.0/i386, 3.0/sgimips and current/alpha.
 
 OK by martin@.
