Subject: [PATCH net-next] selftests: Set default protocol for raw sockets in nettest

From: David Ahern <[email-masked]>
Date: Thu, 17 Sep 2020 09:13:33 -0600

IPPROTO_IP (0) is not valid for raw sockets. Default the protocol for
raw sockets to IPPROTO_RAW if the protocol has not been set via the -P
option.
