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 Signed-off-by: Vinicius Costa Gomes <vinicius.gomes@intel.com> --- drivers/net/ethernet/intel/igc/igc_dump.c | 3 +++ 1 file changed, 3 insertions(+)
