usbnet: speed reporting for devices without MDIO
This series introduces support for USB network devices that report
speed as a part of their protocol, not emulating an MII to be accessed
over MDIO.
v2: rebased on recent upstream changes
v3: incorporated hints on naming and comments
v4: fix misplaced hunks; reword some commit messages;
add same change for cdc_ether
v4-repost: added "net-next" to subject and Andrew Lunn's Reviewed-by
I'm reposting Oliver Neukum's <oneukum@suse.com> patch series with
fix ups for "misplaced hunks" (landed in the wrong patches).
Please fixup the "author" if "git am" fails to attribute the
patches 1-3 (of 4) to Oliver.
I've tested v4 series with "5.12-rc3+" kernel on Intel NUC6i5SYB
and + Sabrent NT-S25G. Google Pixelbook Go (chromeos-4.4 kernel)
+ Alpha Network AUE2500C were connected directly to the NT-S25G
to get 2.5Gbps link rate:
Settings for enx002427880815:
Supported ports: [ ]
Supported link modes: Not reported
Supported pause frame use: No
Supports auto-negotiation: No
Supported FEC modes: Not reported
Advertised link modes: Not reported
Advertised pause frame use: No
Advertised auto-negotiation: No
Advertised FEC modes: Not reported
Speed: 2500Mb/s
Duplex: Half
Auto-negotiation: off
Port: Twisted Pair
PHYAD: 0
Transceiver: internal
MDI-X: Unknown
Current message level: 0x00000007 (7)
drv probe link
Link detected: yes
"Duplex" is a lie since we get no information about it.
I expect "Auto-Negotiation" is always true for cdc_ncm and
cdc_ether devices and perhaps someone knows offhand how
to have ethtool report "true" instead.
But this is good step in the right direction.

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.
