Michal Swiatkowski 8d2e34e4e2 ice: tc: allow zero flags in parsing tc flower 
[ Upstream commit 7327871572 ]

The check for flags is done to not pass empty lookups to adding switch
rule functions. Since metadata is always added to lookups there is no
need to check against the flag.

It is also fixing the problem with such rule:
$ tc filter add dev gtp_dev ingress protocol ip prio 0 flower \
	enc_dst_port 2123 action drop
Switch block in case of GTP can't parse the destination port, because it
should always be set to GTP specific value. The same with ethertype. The
result is that there is no other matching criteria than GTP tunnel. In
this case flags is 0, rule can't be added only because of defensive
check against flags.

Fixes: 9a225f81f5 ("ice: Support GTP-U and GTP-C offload in switchdev")

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.
