The ThunderX NIC has two Ethernet Interfaces (BGX) each of them could has up to four Logical MACs configured. Each of BGX has 32 filters to be configured for filtering ingress packets. The number of filters available to particular LMAC is from 8 (if we have four LMACs configured per BGX) up to 32 (in case of only one LMAC is configured per BGX). At the same time the NIC could present up to 128 VFs to OS as network interfaces, each of them kernel will configure with set of MAC addresses for filtering. So to prevent dupes in BGX filter registers from different network interfaces it is required to cache and track all filter configuration requests prior to applying them onto BGX filter registers. This commit is to update LMAC structures with control fields to allocate/releasing filters tracking list along with implementing dmac array allocate/release per LMAC.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
