[PATCH net-next] net: phy: add extension of phy-mode for XLGMII

The Synopsys DWC_xlgmac core provides a multiplexed 40-Gigabit
Media-Independent Interface (XLGMII, an IEEE 802.3 Clause 81
compliant reconciliation sub-layer) for communication with
the 100/50/40/25-Gigabit PHY and 10-Gigabit Media-Independent
Interface (XGMII, an IEEE 802.3 Clause 46 compliant reconciliation
sub-layer) for communication with the 10-Gigabit PHY.

Currently, There are only interface mode definitions for "xgmii".
This patch adds the definitions for the PHY layer to recognize
"xlgmii" as a valid PHY interface.

It makes no sense to add these definitions unless you also submit
uses of them alongside at the same time.

Thanks.

Correct, also, this is incomplete, you must include a change to
Documentation/devicetree/bindings/net/ethernet.txt to reflect this new mode.

Thank you
