SOL_IP provides a way to configure network layer attributes in a socket. This patch adds support for IP_TOS for setsockopt(.. ,SOL_IP, ..) Support for SOL_IP is added in mptcp_setsockopt() and IP_TOS is handled in a private function. The idea here is to take in the value passed for IP_TOS and set it to the current subflow, open subflows as well new subflows that might be created after the initial call to setsockopt(). This sync is done using sync_socket_options(.., ssk) and setting the value of tos using __ip_sock_set_tos(ssk,..). The patch has been tested using the packetdrill script here - https://github.com/multipath-tcp/mptcp_net-next/issues/220#issuecomment-947863717 Closes: https://github.com/multipath-tcp/mptcp_net-next/issues/220 Signed-off-by: Poorva Sonparote <psonparo@redhat.com> Signed-off-by: Mat Martineau <mathew.j.martineau@linux.intel.com> Signed-off-by: David S.

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.
