Calls to LOG_DEBUG should ideally be hidden behind some sort of flag, and off by default. Logging on Android is very costly and should be avoided as much as possible, especially where there might be a lot of data logged.

@simonrozsival we can also remove this one, it is unused in mono now

HAVE_GETIFADDRS is still used, for example here: https://github.com/dotnet/runtime/pull/71943/files#diff-404dd4500e99144ae93b6753065902099e05f7fc7ef19834d0d6e152ed0e6b45R253

@simonrozsival that is part of System.Native, not mono. It has its own check:

In recent Android versions the data returned by
getifaddrsis invalid and doesn't allow us to implementSystem.Net.NetworkInformation.GetAllNetworkInterfaces(). It's possible to reimplementgetifaddrsusing Netlink and there's already an existing implementation in Xamarin.Android.Fixes dotnet/android#6973
