Field Documentation

SEQ value, in host-endian order.

This represents the SEQ value at the time the packet is enqueued, and so excludes the SYN, if present.

Next SEQ value, in host-endian order.

Referenced by tcp_rx_enqueue(), and tcp_sack_block().

Flags.

Only FIN is valid within this flags byte; all other flags have already been processed by the time the packet is enqueued.
