Subject: [PATCH 5.4 26/38] selftests: forwarding: fix learning_test when h1 supports IFF_UNICAST_FLT
From: Vladimir Oltean <vladimir.oltean@....com>
[ 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.
Fixes: d4deb01467ec ("selftests: forwarding: Add a test for FDB learning")
