it was e.g.:

	lsblk: /dev/md: not a block device
	lsblk: /dev/md: not a block device

now:

	# md1 (raid0) -> sda3  sdb3
	# sda: SAMSUNG MZ7LN256  rev 100Q 238.5G
	# sdb: SAMSUNG MZ7LN256  rev 100Q 238.5G

So just extract machine global IP addresses at runtime as configured on
the interfaces.

neotest part pending.

On neo1 - neo2 without TSO latency becomes very poor in lat_tcp when
payload size becomes greater TCP MSS (lat_tcp -m 1448 ~ 130μs; lat_tcp
-m 1449 ~ 500μs and more)

e.g.

	neotest cpustat ls
