This is an USB-to-Ethernet Bridge example that demonstrates
USB Communication Device Class (CDC) Network Control Model (NCM) class
on USB Device.

It demonstrates a bridge between PC Network and Ethernet port on the
evaluation board.

Board:                  Atmel         'SAMV71-XULTRA'
Microcontroller:        Atmel           'ATSAMV71Q21'
Clock Settings:         XTAL                =  12 MHz
                        PLLA                = 600 MHz
                        Main clock = PLLA/2 = 300 MHz

The program is available for target(s):

  SAMV7 Flash DAP:        runs from Internal Flash located on chip
                          uses on-board CMSIS-DAP debugger

  SAMV7 Flash ULINK Pro:  runs from Internal Flash located on chip
                          uses ULINK Pro Cortex debugger

Note: On revision 6 of SAM V71 Xplained Ultra the TX and RX differential 
      pairs has a swapped position on the RJ-45 connector compared to 
      what is normal (try crosslink cable if link is always down).
