Got new machine setup with XL710 NIC's and testing out DPDK.
When device is first used by DPDK see these messages.
Which are at warning level which by definition means something is wrong.
And the messages are unhelpful; they mean some to the developer but not to a user.

Agree with this assessment.
Now submitted patch to reduce log level to INFO[1]
