Greg Thelen d3210dabda eth: mlx4: select PAGE_POOL
With commit 8533b14b3d ("eth: mlx4: create a page pool for Rx") mlx4
started using functions guarded by PAGE_POOL. 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.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
