Florian Fainelli d2223fd3dd net: Always descend into dsa/ folder with CONFIG_NET_DSA enabled 
[ Upstream commit b1fa60ec25 ]

Stephen reported that he was unable to get the dsa_loop driver to get
probed, and the reason ended up being because he had CONFIG_FIXED_PHY=y
in his kernel configuration. As Masahiro explained it:

  "obj-m += dsa/" means everything under dsa/ must be modular.

  If there is a built-in object under dsa/ with CONFIG_NET_DSA=m,
  you cannot do  "obj-$(CONFIG_NET_DSA) += dsa/".

  You need to change it back to "obj-y += dsa/".

This was the case here whereby CONFIG_NET_DSA=m, and so the
obj-$(CONFIG_FIXED_PHY) += dsa_loop_bdinfo.o rule is not executed and
the DSA loop mdio_board info structure is not registered with the
kernel, and eventually the device is simply not found.

To preserve the intention of the original commit of limiting the amount
of folder descending, conditionally descend into drivers/net/dsa when
CONFIG_NET_DSA is enabled.

README 

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 Restructured Text 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.
