Message

changes v2:
- make this tests available for all netowking devices.
- enable them on FEC, ag71xx and all DSA switches.
- add and test loopback support on more PHYs.

This patch set provides diagnostic capabilities for some iMX, ag71xx or
any DSA based devices. For proper functionality, PHY loopback support is
needed.
So far there is only initial infrastructure with basic tests.
