Greeting,

FYI, we noticed the following commit (built with gcc-11):

commit: 2ef23e860e765eb1dd287492206d833f04eae9df ("vrf: packets with lladdr src needs dst at input with orig_iif when needs strict")
https://github.com/ammarfaizi2/linux-block testing/for-5.4-lts

in testcase: kernel-selftests

with following parameters:

	group: net
	test: fcnal-test.sh
	atomic_test: use_cases
	ucode: 0xf0

test-description: The kernel contains a set of "self tests" under the tools/testing/selftests/ directory. These are intended to be small unit tests to exercise individual code paths in the kernel.

FYI, we noticed that this is a backport commit of upstream 205704c618af0ab2366015d2281a3b0814d918a0
(merged by v5.10), so we also test this case on mainline, and this issue doesn't exist.


To reproduce:

         git clone https://github.com/intel/lkp-tests.git
         cd lkp-tests
         sudo bin/lkp install job.yaml           # job file is attached in this email
         bin/lkp split-job --compatible job.yaml # generate the yaml file for lkp run
         sudo bin/lkp run generated-yaml-file

         # if come across any failure that blocks the test,
         # please remove ~/.lkp and /lkp dir to run from a clean state.
