From 64eccd0066775aaf7442761413b3cac137c00ced Mon Sep 17 00:00:00 2001 From: Jiri Pirko Date: Sun, 8 Jul 2018 23:51:20 +0300 Subject: mlxsw: spectrum_acl: Split TCAM handling 3 ways To allow easy and clean Spectrum-2 implementation for things that differ from Spectrum, split the existing ACL TCAM code 3 ways: 1) common code that calls Spectrum/Spectrum-2 specific ops 2) Spectrum ops implementations 3) common C-TCAM code that is going to be shared between Spectrum and Spectrum-2 implementations Signed-off-by: Jiri Pirko Signed-off-by: Ido Schimmel Signed-off-by: David S.
