Xin Long 0c06d166ea lwtunnel: ignore any TUNNEL_OPTIONS_PRESENT flags set by users
TUNNEL_OPTIONS_PRESENT (TUNNEL_GENEVE_OPT|TUNNEL_VXLAN_OPT|
TUNNEL_ERSPAN_OPT) flags should be set only according to
tb[LWTUNNEL_IP_OPTS], which is done in ip_tun_parse_opts().

When setting info key.tun_flags, the TUNNEL_OPTIONS_PRESENT
bits in tb[LWTUNNEL_IP(6)_FLAGS] passed from users should
be ignored.

While at it, replace all (TUNNEL_GENEVE_OPT|TUNNEL_VXLAN_OPT|
TUNNEL_ERSPAN_OPT) with 'TUNNEL_OPTIONS_PRESENT'.

Fixes: 3093fbe7ff ("route: Per route IP tunnel metadata via lightweight tunnel")
Fixes: 32a2b002ce ("ipv6: route: per route IP tunnel metadata via lightweight tunnel")

README

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.
