Experimental ENET Driver

========================



Current default ethernet driver is eth_mcux, with binding `nxp,kinetis-ethernet`. There is a new

driver with binding `nxp,enet`, which is experimental and undergoing development, but will have

enhanced capability, such as not hardcoding code for only one phy in the driver like eth_mcux.



To build for this EVK with the new driver, include the experimental overlay to west build with

the option `-DEXTRA_DTC_OVERLAY_FILE=nxp,enet-experimental.overlay`.
