Subject: [PATCH net v2 0/2] fixes for Q-USGMII speeds and autoneg

This is the second version of a small changeset for QUSGMII support,
fixing inconsistencies in reported max speed and control word parsing.

As reported here [1], there are some inconsistencies for the Q-USGMII
mode speeds and configuration. The first patch in this fixup series
makes so that we correctly report the max speed of 1Gbps for this mode.

The second patch uses a dedicated helper to decode the control word.
This is necessary as although USGMII control words are close to USXGMII,
they don't support the same speeds.

Thanks,

Maxime
