ASPM issues may result in the NIC not being accessible any longer. In this case disabling ASPM may not work. Therefore detect this case by checking whether register reads return ~0, and try to make the NIC accessible again by resetting the secondary bus. v2: - add exception handling for the case that pci_reset_bus() fails Suggested-by: Alexander Duyck <alexander.duyck@gmail.com> Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Reviewed-by: Alexander Duyck <alexanderduyck@fb.com> Signed-off-by: David S.

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.
