This change introduced build errors when CONFIG_MLX4_EN is set but CONFIG_PAGE_POOL is not: ld: vmlinux.o: in function `mlx4_en_alloc_frags': en_rx.c:(.text+0xa5eaf9): undefined reference to `page_pool_alloc_pages' ld: vmlinux.o: in function `mlx4_en_create_rx_ring': (.text+0xa5ee91): undefined reference to `page_pool_create' Make MLX4_EN select PAGE_POOL to fix the ml;x4 build errors.
