From: Jun Yang <jun.y...@nxp.com>

Support combination of RAW extract and header extracts.
RAW extract can start from any absolute offset.

TBD: relative offset support.
To support relative offset of previous L3 protocol item,
extracts should be expanded to identify if the frame is:
vlan or none-vlan.

To support relative offset of previous L4 protocol item,
extracts should be expanded to identify if the frame is:
vlan/IPv4 or vlan/IPv6 or none-vlan/IPv4 or none-vlan/IPv6.
