* This is a simple test tool to bind netatalk SOCK_DGRAM sockets and perform

* connected endpoints, with the intent of exercising the various kernel send
* case.
*
* In order to run this test, configure NETATALK into the kernel. Use
* ifconfig to set an appletalk address on an interface. Run this tool with
* two arguments: a local address and port number, and a remote address and
* port number.
*
* It is recommended that you try running it with some interesting address
* and port thresholds, including ATADDR_ANYNET, ATADDR_ANYNODE,
* ATADDR_ANYPORT, and ATADDR_ANYBCAST. Try both remote unicast addresses
* and the local address, which will help to test local delivery (although
