Re: [dts] [PATCH] test_plans: add test plan enable_jumboframe_for_vf

["Tu, Lijuan" <lijuan.tu@intel.com>]

1, this test plan is a part of daemon, please add them into test_plans/vf_daemon_test_plan.rst
2, not only support Niantic, but also support Fortville.
3, be care of  your expression, this is a formal document.

[Lijuan] please consider packet size == mtu.
