From d552107f5ce59a69b43517e4327ed6a4903bf529 Mon Sep 17 00:00:00 2001 From: Vadim Kochan Date: Sun, 18 Dec 2016 11:52:46 +0200 Subject: trafgen: proto: Rename proto_field_xxx -> proto_hdr_field_xxx Rename all proto_field_xxx(...) functions to proto_hdr_field(...). It is good for 2 reasons: 1) proto_hdr_field_xxx naming is more consistent as it is related to proto_hdr API. 2) It makes possible to introduce proto_field_xxx API which will operate only with struct proto_field.
