Add support for rewrite of PCP and DEI, based on classified Quality of Service (QoS) class and Drop-Precedence (DP) level. The DCB rewrite table is queried for mappings between priority and PCP/DEI. The classified DP level is then encoded in the DEI bit, if a mapping for DEI exists. Sparx5 has four DP levels, where by default, 0 is mapped to DE0 and 1-3 are mapped to DE1. If a mapping exists where DEI=1, then all classified DP levels mapped to DE1 will set the DEI bit. The other way around for DEI=0. Effectively, this means that the tagged DEI bit will reflect the DP level for any mappings where DEI=1. Map priority=1 to PCP=1 and DEI=1: $ dcb rewr add dev eth0 pcp-prio 1:1de Map priority=7 to PCP=2 and DEI=0 $ dcb rewr add dev eth0 pcp-prio 7:2nd Also, sparx5_dcb_ieee_dscp_setdel() has been refactored, to work for both APP and rewrite entries.

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.
