It's megabits/sec. The QMP query-migration command shows the throughput
in Mbits/s. It includes PSP command execution and the network write.
Most of the time is spent in PSP FW. I have not performed raw PSP
command benchmark yet but I believe SEV FW 0.17 may reproduce up to
12Mbits/s. I will update thread after I finish the further performance
breakdown.
