Linux kernel source tree

Reuse core sending functions to send XSk xmit frames. Both metadata and no metadata pools/driver are supported. libeth_xdp also provides generic XSk metadata ops, currently with the checksum offload only and for cases when HW doesn't require supplying L3/L4 checksum offsets. Drivers are free to pass their own ops. &libeth_xdp_tx_bulk is not used here as it would be redundant; pool->tx_descs are accessed directly. Fake "libeth_xsktmo" is needed to hide implementation details from the drivers when they want to use the generic ops: the original struct is defined in the same file where dev->xsk_tx_metadata_ops gets set to avoid duplication of slowpath; at the same time; XSk xmit functions use local "fast" copy to inline XMO callbacks. Tx descriptor filling loop is unrolled by 8.

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.
