By default, the tagged ingress packets to the switch from the host port P0 get internal switch priority assigned equal to the DMA CPPI channel number they came from, unless CPSW_P0_CONTROL_REG.RX_REMAP_VLAN is enabled. This causes issues with applying QoS policies and mapping packets on external port fifos, because the default configuration is vlan_aware and DMA CPPI channels are shared between all external ports. Hence enable CPSW_P0_CONTROL_REG.RX_REMAP_VLAN so packet will preserve internal switch priority assigned following the VLAN(priority) tag no matter through which DMA CPPI Channels packets enter the switch.

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.
