The MPTCP upstreaming community has prepared a net-next RFCv3 patch set for review. The scope of this patch set is limited to prerequisite TCP core changes so we can get focused feedback in these areas.
In this patch set we introduce some MPTCP definitions, additional ULP and skb extension features, TCP option space checking, and a few exported symbols. Our intent is to send this as a non-RFC series when the next phase of changes are ready to post. That second patch set will add CONFIG_MPTCP in Kconfig, introduce the MPTCP socket type, implement the basic features of the protocol, and add self tests.
