(EVK) Minimum requirements for Cellular on EVK

[PaulZC]

Based on all the recent changes and testing we'd done on Ethernet and WiFi on EVK, here's Paul's take on the minimum requirements for cellular on EVK. Discuss...

Note: cellular operators can be tricky about allowing mobile devices to act as servers with incoming connections. This list assumes that only client (outgoing) connections are required.

Note: there's (currently) no milestone attached to this. Right now, it's more of a wishlist than a development plan...!

Note: the LARA-R6 has built-in FTP / file download functionality. Files can be downloaded to its internal file system and read from there. Firmware update could be very straightforward to implement...

I think we can close this out. v2.2 of the Everywhere firmware is working well for most functions over cellular. I'm not yet able to test TCP Client. TCP/UDP Server seems to be working, but sadly and not surprisingly, it looks like inbound connections are rarely allowed over a cellular connection.
