From b6381d8f9b4d3abbdb05654a0cf87829a848edf1 Mon Sep 17 00:00:00 2001 From: Eli Cohen Date: Wed, 27 May 2020 08:35:03 +0300 Subject: [PATCH] net: Make mpls_entry_encode() available for generic users Move mpls_entry_encode() from net/mpls/internal.h to include/net/mpls.h and make it available for other users. Specifically, hardware driver that offload MPLS can benefit from that.
