igb: SERDES loopback sigdetect bit on i210 devices
This patch implements SERDES loopback configuration for i210 devices by unsetting sigdetect bit, so as to fix Ethtool loopback test failure. Old sigdetect code is also simplified to take care of all devices newer than 82580 Signed-off-by: Akeem G Abodunrin <akeem.g.abodunrin@intel.com> Tested-by: Aaron Brown <aaron.f.brown@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>
