[Stephen Hemminger]

From: Stephen Hemminger <shemming@brocade.com>

Silence is normal. drivers should speak only when spoken to and not
be chatty.

NAK.

The main problem is that enic pmd is using printf to write logs.
So the pmd should be fixed so that dev_* macros use RTE_LOG.

Silence is good when it is the default behaviour.
But I prefer we can change this at runtime, rather than strip the log
messages, especially for init.

Agree it should not use printf.
If you insist on keeping the useless message then it should be log level
debug
