[PATCH net-next v4 0/5] pcs-xpcs, stmmac: add 1000BASE-X AN for network switch

[Ong Boon Leong]

Hi,

Thanks for review feedback from Russell in [1] and [2]. I have changed
the v4 implementation as follow.

v4 changes:
1/5 - Squash v3:1/7 & 2/7 patches into v4:1/6 so that it passes build.
2/5 - [No change] same as v3:3/7
3/5 - [Fix] Fix issues identified by Russell in [1]
4/5 - [Fix] Drop v3:5/7 patch per input by Russell in [2] and make
            dwmac-intel clear the ovr_an_inband flag if fixed-link
            is used in ACPI _DSD.
5/5 - [No change] same as v3:7/7

The patches are built with C=1 and W=1 and I have found no additional
warn and error from these patches (as advised by Jakub)

The record for v3 changes is in [3]
1/7 - [New] Update xpcs_do_config to accept advertising input
2/7 - [New] Fix to compilation issue introduced v1. Update xpcs_do_config
            for sja1105.
3/7 - Same as 3/4 of v1 series.
4/7 - [Fix] Fix numerous issues identified by Russell King.
5/7 - [New] Make fixed-link setting takes precedence over ovr_an_inband.
            This is a fix to a bug introduced earlier. Separate patch
            will be sent later.
6/7 - [New] Allow phy-mode ACPI _DSD setting for dwmac-intel to overwrite
            the phy_interface detected through PCI DevID.
7/7 - [New] Make mdio register flow to skip PHY scanning if fixed-link
            is specified.
