This is not really appropriate.

We have statistics like the ones you are incrementing in this
function as the mechanism people can use to learn what events
happened on an interface, and how many times they happened.

Therefore, emitting a log message for each one of those events too is
not necessary.

We don't emit a netdev_err() for every packet that the IPv4 stack
drops due to a bad checksum, for example.

Please get rid of this.
