From: Maryam Tahhan <[e-mail]>

Add documentation for BPF_MAP_TYPE_DEVMAP and
BPF_MAP_TYPE_DEVMAP_HASH including kernel version
introduced, usage and examples.

Add documentation that describes XDP_REDIRECT. 

v2->v3:
- Update examples in DEVMAPs documentation for broadcast scenario.
- Update key reference for BPF_MAP_TYPE_DEVMAP_HASH (doesn't have to be
  ifindex).
- Remove information re xdp_redirect internals.

v1->v2:
- Separate xdp_redirect documentation to its own file.
- Clean up and simplify examples and usage function descriptions.
