Currently, the filter's protocol is ignored except for a few special
cases (IPv4 and IPv6).
The EtherType can be matched inside VCAP IS2 by using a MAC_ETYPE key.
So there are 2 cases in which EtherType matches are supported:
- As part of a larger MAC_ETYPE rule, such as:
tc filter add dev swp0 ingress protocol ip \
flower skip_sw src_mac 42:be:24:9b:76:20 action drop
- Standalone (matching on protocol only):
tc filter add dev swp0 ingress protocol arp \
flower skip_sw action drop
As before, if the protocol is not specified, is it implicitly "all" and
the EtherType mask in the MAC_ETYPE half key is set to zero.

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.
