A minimal set of features to comply with the specification involves a sizeable set of code changes, so David requested that we split this work in to multiple, smaller patch sets to build up MPTCP infrastructure. The minimal MPTCP feature set we are proposing for review in the v5.6 timeframe begins with these three parts: Part 1 (this patch set): MPTCP prerequisites. Introduce some MPTCP definitions, additional ULP and skb extension features, TCP option space checking, and a few exported symbols. Part 2: Single subflow implementation and self tests. Part 3: Switch from MPTCP v0 (RFC 6824) to MPTCP v1 (new RFC 8684, publication expected in the next few days). We plan to send those over the next week. Additional patches for multiple subflow support, path management, active backup, and other features are in the pipeline for submission after making progress with the above reviews.
