This patch adds to mlx5 drivers support for 8 ports HCAs. Starting with ConnectX-8 HCAs with 8 ports are possible. As most driver parts aren't affected by such configuration most driver code is unchanged. Specially the only affected areas are: - Lag - Multiport E-Switch - Single FDB E-Switch All of the above are already factored in generic way, and LAG and VF LAG are tested, so all that left is to change a #define and remove checks which are no longer needed. However, Multiport E-Switch is not tested yet, so it is left untouched. This patch will allow to create hardware LAG/VF LAG when all 8 ports are added to the same bond device. for example, In order to activate the hardware lag a user can execute the following: ip link add bond0 type bond ip link set bond0 type bond miimon 100 mode 2 ip link set eth2 master bond0 ip link set eth3 master bond0 ip link set eth4 master bond0 ip link set eth5 master bond0 ip link set eth6 master bond0 ip link set eth7 master bond0 ip link set eth8 master bond0 ip link set eth9 master bond0 Where eth2, eth3, eth4, eth5, eth6, eth7, eth8 and eth9 are the PFs of the same HCA.

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 reStructuredText 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.
