From 22a677661f5624539d394f681276171f92d714df Mon Sep 17 00:00:00 2001 From: Jiri Pirko Date: Fri, 3 Feb 2017 10:29:07 +0100 Subject: [PATCH] mlxsw: spectrum: Introduce ACL core with simple TCAM implementation Add ACL core infrastructure for Spectrum ASIC. This infra provides an abstraction layer over specific HW implementations. There are two basic objects used. One is "rule" and the second is "ruleset" which serves as a container of multiple rules. In general, within one ruleset the rules are allowed to have multiple priorities and masks. Each ruleset is bound to either ingress or egress a of port netdevice. The initial TCAM implementation is very simple and limited. It utilizes parman lsort manager to take care of TCAM region layout.
