Subject: [dts][PATCH V1 1/2] test_plans/vhost_qemu_mtu_test_plan: modify testplan
Date: Fri, 24 Jun 2022 05:37:31 -0400 [thread overview]
Message-ID: <20220624093731.2891136-1-weix.ling@intel.com> (raw)
Delete the step 4 as no need to check the MTU value in VM's testpmd,
only need to check the MTU value in VM's kernel and vhost's testpmd.
