This patch adds basic support for EtherType RX frame steering for
LLDP and PTP using the hardware offload capabilities.
Example steps for setting up RX frame steering for LLDP and PTP:
$ IFDEVNAME=eth0
$ tc qdisc add dev $IFDEVNAME ingress
$ tc qdisc add dev $IFDEVNAME root mqprio num_tc 8 \
map 0 1 2 3 4 5 6 7 0 0 0 0 0 0 0 0 \
queues 1@0 1@1 1@2 1@3 1@4 1@5 1@6 1@7 hw 0
For LLDP
$ tc filter add dev $IFDEVNAME parent ffff: protocol 0x88cc \
flower hw_tc 5
OR
$ tc filter add dev $IFDEVNAME parent ffff: protocol LLDP \
flower hw_tc 5
For PTP
$ tc filter add dev $IFDEVNAME parent ffff: protocol 0x88f7 \
flower hw_tc 6
Show tc ingress filter
$ tc filter show dev $IFDEVNAME ingress
v1->v2:
Thanks to Kurt's and Sebastian's suggestion.
- change from __be16 to u16 etype
- change ETHER_TYPE_FULL_MASK to use cpu_to_be16() macro

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.
