[B][SRU][PATCH 3/4] selftests/net: enable msg_zerocopy test

[Po-Hsu Lin]

From: Willem de Bruijn <willemb at google.com>

BugLink: https://bugs.launchpad.net/bugs/1934759

The existing msg_zerocopy test takes additional protocol arguments.
Add a variant that takes no arguments and runs all supported variants.
Call this from kselftest.
