Hey Luca, thanks for the reply!  The requirements in the backports 4.14 menuconfig are listed as follows: Depends on: WLAN [=y] && WLAN_VENDOR_REALTEK [=y] && RTL_CARDS [=m] && m && BP_MODULES [=y] && PCI [=y] I can find the symbol WLAN_VENDOR_REALTEK in the backports 4.14 menuconfig but not in the 3.14 kernel's menuconfig.  Does this mean I can't use the driver with this kernel? -- To unsubscribe from this list: send the line "unsubscribe backports" in
