Packet Processor Engine (PPE) module reads DSA tags from the DMA descriptor and requires untagged DSA packets to properly parse them. Move DSA tag in the DMA descriptor on TX side and read DSA tag from DMA descriptor on RX side. In order to avoid skb reallocation, store tag in skb_dst on RX side. This is a preliminary patch to enable netfilter flowtable hw offloading on EN7581 SoC.

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 reStructuredText 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.
