Looks good, but I would also update the JeeUdp example sketch here

EtherCard/examples/JeeUdp/JeeUdp.ino

Line 252 in 420dd84

ether.sendUdp ((char*) collBuf, collPos, 23456, destIp, config.port);

to get rid of the invalid conversion warning: https://travis-ci.com/github/njh/EtherCard/jobs/367604836#L665-L672

udpClientSendOnly.ino is also affected, as it uses char*:

EtherCard/examples/udpClientSendOnly/udpClientSendOnly.ino

Lines 31 to 37 in 420dd84

	char textToSend[] = "test 123";
	void loop () {
	if (millis() > timer) {
	timer = millis() + 5000;
	//static void sendUdp (char *data,uint8_t len,uint16_t sport, uint8_t *dip, uint16_t dport);
	ether.sendUdp(textToSend, sizeof(textToSend), srcPort, ether.hisip, dstPort );
