[ Upstream commit 520ad89a54edea84496695d528f73ddcf4a52ea4 ]

In some situations, the firmware will return 0 for autoneg supported speed. This may happen if the firmware detects no SFP module, for example. The driver should ignore this so that we don't end up with an invalid autoneg setting with nothing advertised. When SFP module is inserted, we'll get the updated settings from firmware at that time.
