Subject: [PATCH net-next 1/1] Microchip's LAN7800 family USB 2/3 to
10/100/1000 Ethernet device driver
This patch adds a driver for LAN7800 family of USB 2.0 & USB 3.0 to Gigabit Ethernet.
- remove module param which can be configurable by standard mechanism.
- remove other module parms except msg_level per review comment.
