Subject: [RFC PATCH v3 00/10] Multipath TCP prerequisites


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.
