Modified Files:
	src/sys/net: if_ether.h

Log Message:
add several VLAN tagging related macros, to reduce code duplication
in various ethernet adapter drivers and improve code consistency; mostly
FreeBSD-compatible, with exception of VLAN_OUTPUT_TAG(), which takes
(struct ethercom *) rather than (struct ifnet *) as first parameter
since the information cannot be extracted via (struct ifnet)

also add VLAN_ATTACHED(ec), which tests if any VLAN is attached to the
ethernet device
