I read a book about ethernet and it has been written in it " for recognition of collision the minimum No. of UDP data must be 46 bytes" .
I have also a program that sends UDP packet to ethernet but the data field has 3 bytes data and 17 bytes padding .
can you plz tell me
what is the minimum lenght of UDP data (data + padding) in an ethernet whitch uses Type instead of type/lenght field ?
