You didn't specify which one you are talking about, but here's how to
find out...

Assuming rpi3, find the config first...

configs/rpi_3_defconfig says: CONFIG_DEFAULT_DEVICE_TREE="bcm2837-rpi-3-b"
arch/arm/dts/bcm2837-rpi-3-b.dts says: #include "bcm283x-rpi-smsc9514.dtsi"
arch/arm/dts/bcm283x-rpi-smsc9514.dtsi says:                 ethernet:
usbether at 1 {                       compatible = "usb424,ec00";
grep -rn ec00 drivers/ says: drivers/usb/eth/smsc95xx.c

Cheers,
-Joe
