From 2ce124109c0fe0ea03233ae3625583de1f25e89c Mon Sep 17 00:00:00 2001 From: Petr Machata Date: Thu, 19 Mar 2020 15:47:21 +0200 Subject: net: tc_skbedit: Make the skbedit priority offloadable The skbedit action "priority" is used for adjusting SKB priority. Allow drivers to offload the action by introducing two new skbedit getters and a new flow action, and initializing appropriately in tc_setup_flow_action().
