NOTE: The click shield fits close to the Arduino connect and cannot be
installed directly because it hits the RJ45 connector. You have to get
some extra Arduino connectors to raise the Click shield so that it clears
the RJ45.

2017-08-16: Configurations added. Initially, I saw hangs i
mrf24j40_reset() before the NSH appears on the serial console.
Unlike the SAMV71-XULT, the SPI looks clean, but was hanging
nevertheless.
Then, on subsequent testing, it "magically" started behaving
properaly and seems quite stable now.. although I did nothing to
the the problem. Perhaps the radio was in a bad state for awhile;
perhaps something I did masked the problem. However, all is well
for the time being.

seems to be some issue with the SPI communications.
2017-08-16: I believe that there is something interfering with the
MRF24J40 on the SPI0. There are other things on the bus. The
MRF24J40 requires sole use of the SPI bus because it holds MISO
low when not selected.
I successfully brought the same logic up on the SAME70-Xplained.
The SPI signals look clean on the board and the MRF24J40 seems
fully functional.
