Some drivers want to access the data transmitted in order to implement acceleration features of the NICs. It is also useful in AF_XDP TX flow. Change the xsk_umem_consume_tx API to return the whole xdp_desc, that contains the data pointer, length and DMA address, instead of only the latter two. Adapt the implementation of i40e and ixgbe to this change.

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.
