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'.

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.
