From 1158f79f82d437093aeed87d57df0548bdd68146 Mon Sep 17 00:00:00 2001 From: David Ahern Date: Mon, 4 Apr 2022 09:09:08 -0600 Subject: ipv6: Fix stats accounting in ip6_pkt_drop VRF devices are the loopbacks for VRFs, and a loopback can not be assigned to a VRF. Accordingly, the condition in ip6_pkt_drop should be '||' not '&&'.
