UDP_TX_PACKET_MAX_SIZE in Ethernet.h is some forgotten define. The only current use is in the UDPSendReceiveString example for the size of the receive buffer. 24 is really not enough there. It causes confusion. https://stackoverflow.com/questions/57467523/arduino-ethernet-shield-not-receiving-udp-packets-correctly

Confirmed. Constant UDP_TX_PACKET_MAX_SIZE should be moved to the example. @jandrassy you should create a pull request.
