Presently the HNS driver enables the HNS H/W error interrupts after the dev initialization is completed. However some exceptions such as NCSI errors can occur when the network port driver is not loaded and those errors required reporting to the BMC. Therefore the firmware enabled all the HNS ras error interrupts before the driver is loaded. And in some cases, there will be some H/W errors remained unclear before reboot. Thus the HNS driver needs to process and recover those hw errors occurred before HNS driver is initialized. This patch adds processing of the HNS hw errors(RAS and MSI-X) which occurred before the driver initialization. For RAS, because they are enabled by firmware, so we can detect specific bits, then log and clear them. But for MSI-X which can not be enabled before open vector0 irq, we can't detect the specific error bits, so we just write 1 to all interrupt source registers to clear.

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.
