This is a note to let you know that I've just added the patch titled selftests: forwarding: fix learning_test when h1 supports IFF_UNICAST_FLT to the 5.18-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: selftests-forwarding-fix-learning_test-when-h1-suppo.patch and it can be found in the queue-5.18 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 79c630b236d282794a6dc4c3418447582c9af900 Author: Vladimir Oltean <vladimir.oltean@xxxxxxx> Date: Sun Jul 3 10:36:25 2022 +0300 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.
