This patch added a new member named csum in struct mptcp_ext, implemented a new function named mptcp_generate_data_checksum(). Generate the data checksum in mptcp_sendmsg_frag, save it in mpext->csum. Note that we must generate the csum for zero window probe, too. Do the csum update incrementally, to avoid multiple csum computation when the data is appended to existing skb. Note that in a later patch we will skip unneeded csum related operation. Changes not included here to keep the delta small.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
