====================
This set brings in the rest of map offload code held up by urgent
fixes and improvements to the BPF arrays.

The first 3 patches take care of array map offload, similarly to
hash maps the attribute validation is split out to a separate map
op, and used for both offloaded and non-offloaded case (allocation
only happens if map is on the host).  Offload support comes down
to allowing this map type through the offload check in the core.
NFP driver also rejects the delete operation in case of array maps.

Subsequent patches add reporting of target device in a very similar
way target device of programs is reported (ifindex+netns dev/ino).
Netdevsim is extended with a trivial map implementation allowing us
to test the offload in test_offload.py.

Last patch adds a small busy wait to NFP map IO, this improves the
response times which is especially useful for map dumps.
