Implement XSK NDOs (setup, wakeup) and create XSK Rx and Tx queues. xsk_qid stores the queue id for a given port which has been registered for zero copy AF_XDP and used to acquire UMEM pointer if registered. Based on the xsk_qid and the xsk_pool (umem) the driver is either in copy or zero copy mode. In case of copy mode the xsk_qid value will be invalid and will be set to valid queue id when enabling zero copy. To enable zero copy, the Rx queues are destroyed, i.e., descriptors pushed to fq and cq are freed to remap them to xdp buffers from the umem.

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.
