I don't have a stmmac-based setup to judge in person. But to me, these
still look too chatty, for being things that user space can always query
through netlink.

1070 »       netdev_info(priv->dev, "configured EST\n");
1090 »       netdev_info(priv->dev, "disabled FPE\n");

Also, they don't seem to be balanced. We don't have "disabled EST" and
"enabled FPE"?! I wonder if "disabled FPE" is actually a typo and should
have been "disabled EST"?

What do you think, should these also be suppressed / deleted?
