Rahul Lakkireddy says: ==================== cxgb4: add TC-MATCHALL classifier offload This series of patches add support to offload TC-MATCHALL classifier to hardware to classify all outgoing and incoming traffic on the underlying port. Only 1 egress and 1 ingress rule each can be offloaded on the underlying port. Patch 1 adds support for TC-MATCHALL classifier offload on the egress side. TC-POLICE is the only action that can be offloaded on the egress side and is used to rate limit all outgoing traffic to specified max rate. Patch 2 adds logic to reject the current rule offload if its priority conflicts with existing rules in the TCAM. Patch 3 adds support for TC-MATCHALL classifier offload on the ingress side. The same set of actions supported by existing TC-FLOWER classifier offload can be applied on all the incoming traffic. v5: - Fixed commit message and comment to include comparison for equal priority in patch 2. v4: - Removed check in patch 1 to reject police offload if prio is not 1. - Moved TC_SETUP_BLOCK code to separate function in patch 1. - Added logic to ensure the prio passed by TC doesn't conflict with other rules in TCAM in patch 2. - Higher index has lower priority than lower index in TCAM. So, rework cxgb4_get_free_ftid() to search free index from end of TCAM in descending order in patch 2. - Added check to ensure the matchall rule's prio doesn't conflict with other rules in TCAM in patch 3. - Added logic to fill default mask for VIID, if none has been provided, to prevent conflict with duplicate VIID rules in patch 3. - Used existing variables in private structure to fill VIID info, instead of extracting the info manually in patch 3. v3: - Added check in patch 1 to reject police offload if prio is not 1. - Assign block_shared variable only for TC_SETUP_BLOCK in patch 1. v2: - Added check to reject flow block sharing for policers in patch 1. - Removed logic to fetch free index from end of TCAM in patch 2. Must maintain the same ordering as in kernel. ==================== 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.
