Since cbb961ca271e ("Use random MAC address when none is given")
Varisys Cyrus P5020 boards have been listing 5 ethernet ports instead of
the 2 the board has.This is because we were preventing the adding of the
unused ports by not suppling them a MAC address, which this patch now
supplies.

match the C ELF ABI calling convention (or the proposed scv convention).
I think we could implement a new ABI by basically duplicating function
entry points with different names.
The ELF v2 ABI convention would suit it
