Compiler warnings #24

Hello, I get many compiler warnings using Teensy 4.1 and native ethernet. Even if everything works perfectly, it pollutes the compiler output and it is not really helpfull. Anything to do about it?

Thanks a lot for your work!

Thanks for your interest in the library, hoping it's working well for you.

Those are informational warnings which are intentionally included to let users know what's happening with the configurations.

I have to use them in the library as there are too many different settings (boards, Ethernet / WiFi shields, etc), without information, it's difficult or impossible to know what wrong with the settings, etc.

If you're sophisticated user, you can know where the warnings are and just simply comment out those warning lines.
