With a clock interval of 400 nsec and a 64 bit transactions (32 bit preamble & 16 bit control & 16 bit data), it is reasonable to assume the mdio transaction will take 25.6 usec. Add a 30 usec delay before the first poll to reduce the chance of a 1000-2000 usec sleep. Reduce the timeout from 1000ms to 100ms as it is unlikely for the bus to take this long.

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.
