Field Documentation

eth_header_t eth_header_snap::header

Ethernet header.

Referenced by eth_prepare_packet(), and eth_process_packet().

eth_ieee_lsap_t eth_header_snap::lsap

LSAP extension.

If DSAP and SSAP are set to ETH_LSAP_SNAP the SNAP extension is being used. If DSAP and SSAP fields are equal to ETH_RAW the raw Ethernet packet without any extensions is being used and the frame content starts rigth after the two fields.

Referenced by eth_prepare_packet(), and eth_process_packet().

eth_snap_t eth_header_snap::snap

SNAP extension.

Referenced by eth_prepare_packet(), and eth_process_packet().
