 kernel-selftests.net.fib_tests.sh.fail


hi, Sriram Yagnaraman,

we noticed two new added tests failed in our test environment.
want to consult with you what's the dependency and requirement to run them?
Thanks a lot!

Hello,

kernel test robot noticed "kernel-selftests.net.fib_tests.sh.fail" on:

commit: 8ae9efb859c05a54ac92b3336c6ca0597c9c8cdb ("selftests: fib_tests: Add multipath list receive tests")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master

in testcase: kernel-selftests
version: kernel-selftests-x86_64-60acb023-1_20230329

	group: net



compiler: gcc-12
