Subject: [PATCH RFC net-next v2 0/3] Add SGMII port support to KSZ9477 switch

From: Tristram Ha <tristram.ha@...rochip.com>

The KSZ9477 switch DSA driver uses XPCS driver to operate its SGMII
port.  After the previous XPCS driver updates are added the XPCS patch
can be used to activate DW_XPCS_SGMII_MODE_MAC_MANUAL for KSZ9477.

The KSZ9477 driver will generate a special value for PMA device ids to
activate the new code.

This will require the previous 4 patches from Russell King about
"net: xpcs: cleanups and partial support for KSZ9477."
