ASIX AX88772B based USB 10/100 Ethernet adapter doesn't come
up ("carrier off"), despite the built-in 100BASE-FX PHY positive link
indication. The internal PHY is configured (using EEPROM) in fixed
100 Mbps full duplex mode.
The primary problem appears to be using carrier_netif_{on,off}() while,
at the same time, delegating carrier management to phylink. Use only the
latter and remove "manual control" in the asix driver.
I don't have any other AX88772 board here, but the problem doesn't seem
specific to a particular board or settings - it's probably
timing-dependent.
Remove unused asix_adjust_link() as well.

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.
