Merge branch 'qed-selftests'

Sudarsana Reddy Kalluru says:

====================
qed/qede: ethtool selftests support.

This series adds the driver support for following selftests:
1. Register test
2. Memory test
3. Clock test
4. Interrupt test
5. Internal loopback test
Patch (1) adds the qed driver infrastructure for selftests. Patches (2) and
(3) add qede driver support for ethtool selftests.

Please consider applying this series to "net-next".
