stable inclusion from stable-v5.10.130 commit 9906c223400fbad19c73605b7b0cf7b14b3ac82f category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I5YRJO

--------------------------------
[ 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.
