Confirmed! Calling that function (before setting real linux mac address)
returns MAC address 00:00:20:07:03:09.

Changing NVS data at position 0x1c-0x21 changes also what above function

So really at position 0x1c-0x21 in NVS data is stored MAC address (in
reverse order). Just default is some unknown 00:00:20:07:03:09.

So MAC address is really part of NVS data.
