[PATCH net-next v3 4/8] igc: Only dump registers if configured to dump HW information

[Vinicius Costa Gomes]

To avoid polluting the users logs with register dumps, only dump the
adapter's registers if configured to do so.

If users want to enable HW status messages they can do:

$ ethtool -s IFACE msglvl hw on
