Most of this patch is about actually supporting XDP_TX action. Pure Tx ZC support is only about looking at XDP_PKT_CONTD presence at options field and based on that generating EOP bit on Tx HW descriptor. This is that simple due to the implementation on xsk_tx_peek_release_desc_batch() where we are making sure that last produced descriptor is an EOP one. Overwrite xdp_zc_max_segs with a value that defines max scatter-gatter count on Tx side that HW can handle.

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.
