Subject: [PATCH v2 net-next 3/5] dsa: add DSA switch driver for Microchip
KSZ9477
From: Woojung Huh <Woojung.Huh@...rochip.com>
The KSZ9477 is a fully integrated layer 2, managed, 7 ports GigE switch
with numerous advanced features. 5 ports incorporate 10/100/1000 Mbps PHYs.
The other 2 ports have interfaces that can be configured as SGMII, RGMII, MII
or RMII. Either of these may connect directly to a host processor or
to an external PHY. The SGMII port may interface to a fiber optic transceiver.
This driver currently supports vlan, fdb, mdb & mirror dsa switch operations.
