Ethernet MAC address.
UDP header.
TCP header.
SCTP header.
IPSec AH header.
IPSec ESP trailer.
IPSec ESP header.
IPv6 Header extensions.
IPv6 header.
IPv4 header.
Simplified IGMP protocol header.
ICMP header.
Simplified GTP protocol header.
IEEE 802.1Q VLAN header.
Ethernet header.
This field is present when the EtherType (the odph_ethhdr_t type field) of the preceding ethernet header is ODPH_ETHTYPE_VLAN. The inner EtherType (the odph_vlanhdr_t type field) then indicates what comes next. Note that the so called TPID field isn't here because it overlaps with the odph_ethhdr_t type field.
Contains 8-bit gtp_hdr_info, 8-bit msg_type, 16-bit plen, 32-bit teid. No optional fields and next extension header.
Contains 8-bit type, 8-bit code, 16-bit csum, 32-bit group. No optional fields and next extension header.
