Introduce PHY listing and link_topology tracking
This is V18 of the phy_link_topology series, aiming at improving support
for multiple PHYs being attached to the same MAC.
V18 is a simple rebase of the V17 on top of net-next, gathering the
tested-by and reviewed-by tags from Christophe (thanks !).
This iteration is also one patch shorter than V17 (patch 12/14 in V17 is gone),
as one of the patches used to fix an issue that has now been resolved by
Simon Horman in
743ff02152 ethtool: Don't check for NULL info in prepare_data callbacks
As a remainder, here's what the PHY listings would look like :
- eth0 has a 88x3310 acting as media converter, and an SFP module with
an embedded 88e1111 PHY
- eth2 has a 88e1510 PHY
PHY for eth0:
PHY index: 1
Driver name: mv88x3310
PHY device name: f212a600.mdio-mii:00
Downstream SFP bus name: sfp-eth0
Upstream type: MAC
PHY for eth0:
PHY index: 2
Driver name: Marvell 88E1111
PHY device name: i2c:sfp-eth0:16
Upstream type: PHY
Upstream PHY index: 1
Upstream SFP name: sfp-eth0
PHY for eth2:
PHY index: 1
Driver name: Marvell 88E1510
PHY device name: f212a200.mdio-mii:00
Upstream type: MAC

(this branch is compatible with this V18 series)

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.
