Although the link is up, there is no ip assigned on setups with high background
traffic. Nothing is transmitted nor received. The RX error count keeps on
increasing. After several minutes, the RX error count stagnates and the
GigE interface finally gets an ip.
The issue is that mlxbf_gige_rx_init() is called before phy_start().
As soon as the RX DMA is enabled in mlxbf_gige_rx_init(), the RX CI reaches the max
of 128, and becomes equal to RX PI. RX CI doesn't decrease since the code hasn't
ran phy_start yet.
Bring the PHY up before starting the RX.

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.
