[PATCH net 1/2] igb: Enable media autosense for the i350.

[PATCH net 1/2] igb: Enable media autosense for the i350.

[Manfred Rudigier]

This patch enables the hardware feature "Media Auto Sense" also on the
i350. It works in the same way as on the 82850 devices. Hardware designs
using dual PHYs (fiber/copper) can enable this feature by setting the MAS
enable bits in the NVM_COMPAT register (0x03) in the EEPROM.

I will get this 2 patch series sent to intel-wired-lan@lists.osuosl.org
  list so that we can get these patches into review and test for
upstream inclusion.
