I have a question about integrating a Microchip (SMSC) LAN9514 (USB Hub + Ethernet).
I use the Starterkit 2 efusA9 Linux, the Microchip Development board for the LAN9514, and build my Linux using the latest (at the time of writing) F&S buildroot release (B2019.08).
Done so far:
I have enabled the hardware support for the LAN9514 in both the Linux Kernel (Device driver->Network device support->USB Network Adapters->Multi-purpose USB Networking Framework->SMSC LAN95XX based USB 2.0 10/100 ethernet devices) and in U-boot (Device drivers->USB support->USB to Ethernet Controller Drivers->SMSC LAN95x support).
I've tested the USB-hub part in both U-boot and Linux, this works.
But when list my network devices (ip link show) only the onboard ethernet interface is showing. Am I missing something? Do I need something for userland?
