[RFT] stmmac Selftests

[Jose Abreu]

Hi stmmac users,

Since 091810dbded9 ("net: stmmac: Introduce selftests support"), the 
stmmac driver supports ethtool selftests that can help diagnose HW 
mis-configurations and SW programming issues.

I would like to request all stmmac users to try running these tests and 
send the output to this thread so that we can try fix more issues and 
make it more stable.

Appreciate all the info you can gather :)
