From 9cf1f6a8c4cbb7836b838b51b3b02ddf32c6c6a0 Mon Sep 17 00:00:00 2001 From: Alexander Duyck Date: Fri, 28 Oct 2016 11:43:20 -0400 Subject: net: Move functions for configuring traffic classes out of inline headers The functions for configuring the traffic class to queue mappings have other effects that need to be addressed. Instead of trying to export a bunch of new functions just relocate the functions so that we can instrument them directly with the functionality they will need.
