Subject: [PATCH net-next 06/11] selftests: mptcp: add extra_args in do_transfer

From: Geliang Tang <geliang.tang@...e.com>

Instead of using a global variable mptcp_connect, this patch added
a new local variable extra_args in do_transfer() to store the extra
arguments passing to the mptcp_connect commands.

This patch also renamed the speed level 'least' to 'speed_*'. This
more flexible way can avoid the need to add new speed levels in the
future.
