PCP and CFI fields. * Ethernet_type for VLAN encapsulation is tunable, default is 0x8100; * PCP (Priority code point) and CFI (canonical format indicator) is tunable per VID; * Tunable encapsulation to support 802.1q * Encapsulation/Decapsulation code improvements New messages have been added for this netgraph node to support the new features. However, the legacy "vlan" id is still supported and compiled in by default. It can be disabled in a future release. TODO: * Documentation * Examples PR: kern/161908 Submitted by: Ivan <rozhuk.im@gmail.com>
