[ Thanks to the introducion of selftests this series ended up being a misc of improvements and the selftests additions per-se. ]
This introduces selftests support in stmmac driver. We add 9 basic sanity checks and MAC loopback support for all cores within the driver. This way more tests can easily be added in the future and can be run in virtually any MAC/GMAC/QoS/XGMAC platform. Having this we can find regressions and missing features in the driver while at the same time we can check if the IP is correctly working. We have been using this for some time now and I do have more tests to submit in the feature. My experience is that although writing the tests adds more development time, the gain results are obvious. I let this feature optional within the driver under a Kconfig option. Cc: Joao Pinto <jpi...@synopsys.com> Cc: David S.
