Subject: [PATCH net-next 0/2] net: phy: aquantia: indicate rate adaptation

This patch-set introduces a bit into the phy_device
structure to indicate the PHYs ability to do rate
adaptation between the system and line interfaces and
sets this bit for the Aquantia PHYs that have this feature.

By taking into account the presence of the said bit, address
an issue with the LS1046ARDB board 10G interface no longer
working with an 1G link partner after autonegotiation support
was added for the Aquantia PHY on board in

commit 09c4c57f7bc4 ("net: phy: aquantia: add support for auto-negotiation configuration")

As it only worked in other modes besides 10G because the PHY
was not configured by its driver to remove them, this is not
really a bug fix but more of a feature add.
