Ethernet with PTP

This example application demonstrates the operation of the Stellaris
Ethernet controller using the lwIP TCP/IP Stack.  DHCP is used to obtain
an Ethernet address.  If DHCP times out without obtaining an address,
AutoIP will be used to obtain a link-local address.  The address that is
selected will be output to the UART.

A default set of pages will be served up by an internal file system and
the httpd server.

The IEEE 1588 (PTP) software has been enabled in this code to synchronize
the internal clock to a network master clock source.

UART0, connected to the FTDI virtual COM port and running at 115,200,
8-N-1, is used to display messages from this application.
