From 938af5e2710a789da2e7a5eb26ecdedcb68c508e Mon Sep 17 00:00:00 2001 From: Stanislav Zaikin Date: Thu, 3 Dec 2020 19:09:53 +0000 Subject: pppoe: fix VLIB_RX into the pppoe-input node Previously, RX interface for PPPoE packets was set as the original interface. Now it is set as corresponding PPPoE interface in the "pppoe-input" node. We need to do it because otherwise IP or other settings won't be working onto the PPPoE interface (only on original rx interface).
