This change adds the ability for flow steering to classify IPv4/6 packets with MPLS tag (Ethertype 0x8847 and 0x8848) as standard IP packets and hit IPv4/6 classification steering rules. Since IP packets with MPLS tag header have MPLS ethertype, they missed the IPv4/6 ethertype rule and ended up hitting the default filter forwarding all the packets to the same single RQ (No RSS). Since our device is able to look past the MPLS tag and identify the next protocol we introduce this solution which replaces ethertype matching by the device's capability to perform IP version identification and matching in order to distinguish between IPv4 and IPv6. Therefore, when driver is performing flow steering configuration on the device it will use IP version matching in IP classified rules instead of ethertype matching which will cause relevant MPLS tagged packets to hit this rule as well. If the device doesn't support IP version matching the driver will fall back to use legacy ethertype matching in the steering as before.

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.
