The 'imply' selection means the driver can still be a loadable module even if the main driver is built-in, leading to a link error: aarch64-linux-ld: drivers/net/ethernet/cavium/thunder/nicvf_main.o: in function `nicvf_remove': nicvf_main.c:(.text+0x25c): undefined reference to `cavium_ptp_put' aarch64-linux-ld: drivers/net/ethernet/cavium/thunder/nicvf_main.o: in function `nicvf_probe': nicvf_main.c:(.text+0x3080): undefined reference to `cavium_ptp_get' Use a 'select' statement instead.
