From af76c50198d1db136bbf293f3700c80722116831 Mon Sep 17 00:00:00 2001 From: Matan Barak Date: Sun, 20 Aug 2017 15:46:51 +0300 Subject: [PATCH] net/mlx5: Add shim layer between fs and cmd The shim layer allows each namespace to define possibly different functionality for add/delete/update commands. The shim layer introduced here, will be used to support flow steering with the FPGA.
