Tomasz Bursztyka cbd1609bf6 net: statistics: Provide specific Kconfig options
This will help to track only what's wanted (ipv6, tpc, udp, else...) if
needed to.

Tomasz Bursztyka e7af4b8947 samples: net: Fix echo applications setting for 15.4
When zephyr receives a 15.4 frames it allocates 1 RX buf (nbuf) and 1
DATA (buf), and it gets queued on net stack for post processing.

Problem: receiving a lot of frames is just completely nominal and very
fast (timing is critical in radio, and the rx thread of the radio driver
has a high priority, much higher than net stack's rx post processing).
So guess what happens when CONFIG_NET_NBUF_RX_COUNT=10 though let's say
12 packets are coming in?

The RX buffer pools gets empty and soon the system hangs on getting a
newly allocated one.

This proper CONFIG_NET_NBUF_RX_COUNT tweak fixes the issue, however some
future work will reduce the need of so many RX meta buf:
- l2's recv could be called right away at net_recv_data, before queuing
  the buffer for post-processing, but this could affects reception
  timing on radio side, which is critical.
- An l2 pre-processing (in the middle of what current l2 recv does)
  could be implemented, it would be technology depenedent (aka: not
  mandatory on all l2) and could quickly decide what to do and at best
  drop the whole, or at least drop the RX meta buf (frag would still be
  kept). Let's see.

Tomasz Bursztyka f3c1b442ba samples: net: echo apps: Add cc2520 configuration for arduino_101
CC2520 is not embedded on an arduino_101, it is however possible to wire
one, and thus it requires to provide cc2520_configure_gpios() function.
This one, being common to a101 is found in samples/net/common.
