=> printenv cdc_connect_timeout
## Error: "cdc_connect_timeout" not defined

Also, no other CDC ethernet variables.

These are the related env variables from my config header file:

    #define CONFIG_IPADDR       10.0.0.2
    #define CONFIG_SERVERIP     10.0.0.1
    #define CONFIG_NETMASK      255.255.255.0

    #define CONFIG_EXTRA_ENV_SETTINGS \
       "ethact=usb_ether\0" \
       "ethprime=usb_ether\0" \
       "usbnet_hostaddr=00:19:B8:00:00:01\0" \
       "usbnet_devaddr=00:19:B8:00:00:02\0" \
       [...]

And these are my settings for USB:

    /* USB */
    #ifdef    CONFIG_CMD_USB
    #    define CONFIG_EHCI_MXS_PORT0
    #    define CONFIG_USB_MAX_CONTROLLER_COUNT    1
    #    define CONFIG_CI_UDC            /* ChipIdea CI13xxx UDC */
    #    define CONFIG_USB_REG_BASE    0x80080000
    #    define CONFIG_USBD_HS            /* High speed support for usb
    device and usbtty. */
    #    define CONFIG_USB_GADGET_DUALSPEED
    #    define CONFIG_USB_ETHER
    #    define CONFIG_USB_ETH_CDC
    #endif
