I am doing one real time application project using iMX6sl with yocto linux. I want to enable USB_ETHernet support in kernel configuration. I have enabled this by using make menuconfig. But it is not working.SO, i want to know that Is it possible to use both FEC ( Fast Ethernet Controller) and USB_ETH..? and Should i do disable FEC to use USB_ETH..? Or is any other way to enable USB_ETH support in kernel...?
