MikroTik RB22 changed behaviour since 2 patches

[Koen Vandeputte]

Hi all,

I noticed 2 following commits:

9091c9f8cb ath79: mikrotik: compile SWCONFIG and AR8216_PHY as modules
12abb2413a ath79: mikrotik: also compile AG71XX_LEGACY as a module

When testing these changes on my RB922 boards, which have 2 ethernet
ifaces, I noticed a change in behavior.
Both interfaces got swapped without any notification:
So anyone with these boards will suffer from broken iface config upon
upgrade :-) (like i did)

Is this expected behavior?
