Subject: [PATCH] selftests: forwarding: fix learning_test when h1 supports IFF_UNICAST_FLT
Git-commit: 1a635d3e1c80626237fdae47a5545b6655d8d81c
Patch-mainline: v5.19-rc6
References: git-fixes

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.
