From: Wei Ling @ 2023-04-25 9:59 UTC (permalink / raw)
To: dts; +Cc: Wei Ling
1.Optimize the verify the expected value from the hard code to read from
conf/pvp_qemu_multi_paths_port_restart.cfg to adapt different platform.
2.Add new conf/pvp_qemu_multi_paths_port_restart.cfg to save the test
parameters and expected vaule to verify running vaule.
