From 1b74fe2e8f5ced78001cf5efd5d24cd304b4c538 Mon Sep 17 00:00:00 2001 From: Vladimir Oltean Date: Sun, 3 Jul 2022 10:36:25 +0300 Subject: [PATCH] selftests: forwarding: fix learning_test when h1 supports IFF_UNICAST_FLT [ Upstream commit 1a635d3e1c80626237fdae47a5545b6655d8d81c ] The first host interface has by default no interest in receiving packets MAC DA de:ad:be:ef:13:37, so it might drop them before they hit the tc filter and this might confuse the selftest. Enable promiscuous mode such that the filter properly counts received packets.
