const (
Reserved = nextReserved // Opaque data.

Constants defined for various ether types in network byte order.
Variables ¶

var HeaderNext = map[fwdpb.PacketHeaderId]uint16{ fwdpb.PacketHeaderId_PACKET_HEADER_ID_IP4: nextIP4, fwdpb.PacketHeaderId_PACKET_HEADER_ID_IP6: nextIP6, fwdpb.PacketHeaderId_PACKET_HEADER_ID_ARP: nextARP, }
HeaderNext maps packet headers to ether-types.
View Source
var NextHeader = map[uint16]fwdpb.PacketHeaderId{}
NextHeader maps ether-types to packet header.

Types ¶
type Ethernet ¶
type Ethernet struct {
// contains filtered or unexported fields
}
An Ethernet presents a ethernet header. It can parse, query, add, remove and operate on Ethernet headers in the packet with zero, one and two vlan tags.
func (*Ethernet) ID ¶
func (eth *Ethernet) ID(int) fwdpb.PacketHeaderId
ID returns the ethernet header's ID.
func (*Ethernet) Modify ¶
func (eth *Ethernet) Modify(id fwdpb.PacketHeaderId) error
Modify modifies an existing ethernet header by adding vlan tags.
