Hi, How differently are TCP packets treated compared to e.g. SCTP packets, while traversing the FreeBSD network stack (up to and including the IP-layer when using ipfw)?.

Are there a lot of TCP-specific optimizations conducted by lower layers anyways (besides possible checksum offloading)? BR, Per
