From a5135bcfba7345031df45e02cd150a45add47cf8 Mon Sep 17 00:00:00 2001 From: Willem de Bruijn Date: Sat, 7 Jan 2017 17:06:36 -0500 Subject: net-tc: convert tc_verd to integer bitfields Extract the remaining two fields from tc_verd and remove the __u16 completely. TC_AT and TC_FROM are converted to equivalent two-bit integer fields tc_at and tc_from. Where possible, use existing helper skb_at_tc_ingress when reading tc_at. Introduce helper skb_reset_tc to clear fields. Not documenting tc_from and tc_at, because they will be replaced with single bit fields in follow-on patches.
