As part of the QoS model, on xmit, the HW mandates that all packets going through a given SQ have the same priority. To align hairpin SQs with that, we use the priority given as part of the matching for the hairpin hash key. This ensures that flows/packets mapped to different HW priorities will go through different hairpin instances. If no priority is given for matching, we treat that as an 8th priority, this is in order not to harm cases where priority is specified. Only the PCP priority trust model is supported.

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.
