Add TC-MATCHALL classifier ingress offload support. The same actions supported by existing TC-FLOWER offload can be applied to all incoming traffic on the underlying interface. Ensure the rule priority doesn't conflict with existing rules in the TCAM. Only 1 ingress matchall rule can be active at a time on the underlying interface. v5: - No change. v4: - Added check to ensure the matchall rule's prio doesn't conflict with other rules in TCAM. - Added logic to fill default mask for VIID, if none has been provided, to prevent conflict with duplicate VIID rules. - Used existing variables in private structure to fill VIID info, instead of extracting the info manually. v3: - No change. v2: - Removed logic to fetch free index from end of TCAM. Must maintain same ordering as in kernel. Signed-off-by: Rahul Lakkireddy <rahul.lakkireddy@chelsio.com> Signed-off-by: David S. Miller <davem@davemloft.net>
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.
