The protocol match function allows the application to define filters based on the protocol information found by the frame decoder (see Frame Decoding).
Functionality of the protocol match function:
- The encapsulations, outer and inner protocols and tunnel types described in Frame Classification.
- Arbitrary values for the outer and inner Protocol (IPv4) and Next Header (IPv6) fields (in addition to the Layer 4 protocols UDP, TCP, ICMP and SCTP).
- MAC destination address type: control frame, broadcast, multicast or unicast frame.
- Fragment test: Not a fragment, first, middle or last fragment.
