Subject: [PATCH net-next 6/6] selftests: mptcp: connect: cover splice mode

From: Geliang Tang <tanggeliang@...inos.cn>

The "splice" alternate mode for mptcp_connect.sh/.c is available now,
this patch adds mptcp_connect_splice.sh to test it in the MPTCP CI by
default.

Note that this mode is also supported by stable kernel versions, but
optimised in this patch series.
