Ethernet.setHostname added (hostname to send with DHCP request) #233

Open JAndrassy opened 12 months ago

JAndrassy commented 12 months ago

There is already a PR for setHostname to set the hostname sent with the DHCP request and some older PR which don't use the setHostname() setter.

I provide my approach which doesn't store the hostname internally to save memory. I added the same code to my EthernetENC library. If setHostname is not used from the sketch the old code with the default hostname is executed.
