For retrieving info like interface MAC addresses, packet parser key extraction config etc currently a command is sent to firmware and firmware which periodically polls for commands, processes these and returns the info. This is resulting in interface initialization taking lot of time. To optimize this a memory region is shared between firmware and this driver, firmware while booting puts static info like these into that region for driver to read directly without using commands. With this - Logic for retrieving packet parser extraction config via commands is removed and repalced with using the shared 'fwdata' structure. - Now RVU MSIX vector address is also retrieved from this fwdata struct instead of from CSR. Otherwise when kexec/kdump crash kernel loads CSR will have a IOVA setup by primary kernel which impacts RVU PF/VF's interrupts. - Also added a mbox handler for PF/VF interfaces to retrieve their MAC addresses from AF.

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.
