hi, Akihiko Odaki,

sorry for sending again, the previous one has some problem that lost most of CC part.

Hello,

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

commit: c04079dfb34c2f534f013408b12218c14b286b7d ("[RFC PATCH 6/7] selftest: tun: Add tests for virtio-net hashing") url: https://github.com/intel-lab-lkp/linux/commits/Akihiko-Odaki/net-skbuff-Add-... base: https://git.kernel.org/cgit/linux/kernel/git/shuah/linux-kselftest.git next patch link: https://lore.kernel.org/all/20231008052101.144422-7-akihiko.odaki@daynix.com... patch subject: [RFC PATCH 6/7] selftest: tun: Add tests for virtio-net hashing

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

group: net test: fcnal-test.sh atomic_test: ipv6_runtime
