This patch changes the way the driver advertises its checksum offload capabilities within the net device features bit mask. Instead of advertising protocol specific checksumming capabilities which are limited today to IPv4 and IPv6, we move to reporing generic HW checksumming capabilities. This will allow the network stack to let mlx5 device offload checksum for cases where the IP header is encapsulated within another protocol and the skb->protocol doesn't indicate one of the IP versions protocol, specifically in the case of MPLS label encapsulating the IP header and the skb->protocol indiciates MPLS ethertype rather than IP. Moving the HW_CSUM reporting is required in the basic net device hw features mask and also in the extensions (vlan and encpasulation features) since the extensions are always multiplied by the basic features set during the packet's traversal through the stack's tx flow.

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.
