Detailed Description

Extended pseudo-header for ERF multi-channel (MC) packet records.

This structure builds on the basic ERF header to support multi-channel packet formats, including optional extended headers and protocol-specific subheaders. It is used in advanced ERF capture scenarios such as DAG cards with multiple input streams or specialized framing.

aal2_hdr

uint32_t erf_mc_phdr::aal2_hdr

AAL2-specific header value.

ehdr_list

struct erf_ehdr erf_mc_phdr::ehdr_list[MAX_ERF_EHDR]

Array of extended ERF headers (e.g., channel, color, hash).

eth_hdr

struct wtap_erf_eth_hdr erf_mc_phdr::eth_hdr

Ethernet-specific subheader.

mc_hdr

uint32_t erf_mc_phdr::mc_hdr

Multi-channel header value.

phdr

struct erf_phdr erf_mc_phdr::phdr

Base ERF header containing timestamp, type, and length metadata.

[union]

union { ... } erf_mc_phdr::subhdr

Protocol-specific subheader union.

Contains additional metadata depending on the ERF record type.
