-Subject: [PATCH] net/usb/r8153_ecm: support ECM mode for RTL8153
-
-commit c1aedf015ebdd0232757a66e2daccf1246bd609c upstream.
-
-Support ECM mode based on cdc_ether with relative mii functions,
-when CONFIG_USB_RTL8152 is not set, or the device is not supported
-by r8152 driver.
-
-Both r8152 and r8153_ecm would check the return value of
-rtl8152_get_version() in porbe(). If rtl8152_get_version()
-return none zero value, the r8152 is used for the device
-with vendor mode. Otherwise, the r8153_ecm is used for the
-device with ECM mode.
