Oliver Schmidt e83fe9a9fe Added support using the W5100 with a single socket.
The W5100 has the undocumented feature to wrap around the Address Register on an Auto-Increment at the end of physical address space to its beginning.

However, the only way to make use of that feature is to have only a single socket that uses all of the W5100 physical address space. But having only a single socket by defining SINGLE_SOCKET comes with downsides too:

One mustn't call into IP65 network functions anymore after w5100_config(). Additionally the program doesn't support 'W5100 Shared Access' anymore (https://github.com/a2retrosystems/uthernet2/wiki/W5100-Shared-Access).
