Yeah, we break regular ethernet wake-on-lan too
So we need a
more device-type-agnostic fix. I've filed a bug about this:

I'm not sure if situation is both cases is the same. Ethernet seems
to be issue that NM does not accept ETHTOOL_OPTS parameter which
enable WoL, but if you enable that on udev script (or by hand), 
IIUC WoL will work - NM does not wipe out settings.

WoWLAN case is that, when we enable WoWLAN externally, setting will 
not take an effect due to disconnection.

I understand that good solution will be adding NM option (config or GUI)
that enable WoL for interface and then act properly. But still then we
will have to cope with not-disconnecting on suspend and NL80211
