Subject: Re: [PATCH v2] selftests: net: Correct case name

hi,

  I try to test the "selftests: Fix raw socket bind tests with VRF" patch.
  https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net.git/commit/?id=0f108ae44520

  But the TEST: Raw socket bind to local address - ns-A IP  which used to be passed became failed.

best regards,
