Currently, VF to PF interrupt handling is based on the DH895XCC device behavior, which is not entirely common to all devices. In order to make interrupt detection and handling correct for all of the supported devices, make the interrupt handling device specific by: - introducing get_vf2pf_sources() for getting a 32 bits long value where each bit represents a vf2pf interrupt; - adding the device [enable|disable]_vf2pf_interrupts to hw_data; - defining [enable|disable]_vf2pf_interrupts for all the devices that are currently supported, using only their required and specific ERRSOU|ERRMASK registers (DH895XCC has 32 interrupts spread across ERRSOU3 and ERRSOU5, C62X/C3XXX has 16 in ERRSOU3 only, etc). Code has been shared by different devices wherever possible. This patch is based on earlier work done by Salvatore Benedetto.

README
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.
