Fix the sending of a single packet (or small burst) in xdpsock when executing in copy mode. Currently, the l2fwd application in xdpsock only transmits the packets after a batch of them has been received, which might be confusing if you only send one packet and expect that it is returned pronto. Fix this by calling sendto() more often and add a comment in the code that states that this can be optimized if needed.

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.
