Added new mailbox messages to install and delete MCAM rules. These mailbox messages will be used for adding/deleting ethtool n-tuple filters by NIX PF. The installed MCAM rules are stored in a list that will be traversed later to delete the MCAM entries when the interface is brought down or when PCIe FLR is received. The delete mailbox supports deleting a single MCAM entry or range of entries or all the MCAM entries owned by the pcifunc. Each MCAM entry can be associated with a HW match stat entry if the mailbox requester wants to check the hit count for debugging. Modified adding default unicast DMAC match rule using install flow API. The default unicast DMAC match entry installed by Administrative Function is saved and can be changed later by the mailbox user to fit additional fields, or the default MCAM entry rule action can be used for other flow rules installed later. Modified rvu_mbox_handler_nix_lf_free mailbox to add a flag to disable or delete the MCAM entries. The MCAM entries are disabled when the interface is brought down and deleted in FLR handler. The disabled MCAM entries will be re-enabled when the interface is brought up again.

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.
