Subject: [RFC PATCH v3 03/10] tcp: Define IPPROTO_MPTCP
Date: Wed, 9 Oct 2019 16:08:02 -0700 [thread overview]
Message-ID: <20191009230809.27387-4-mathew.j.martineau@linux.intel.com> (raw)
In-Reply-To: <20191009230809.27387-1-mathew.j.martineau@linux.intel.com>
To open a MPTCP socket with socket(AF_INET, SOCK_STREAM, IPPROTO_MPTCP),
IPPROTO_MPTCP needs a value that differs from IPPROTO_TCP. The existing
IPPROTO numbers mostly map directly to IANA-specified protocol numbers.
MPTCP does not have a protocol number allocated because MPTCP packets
use the TCP protocol number. Use private number not used OTA.
