This patch implement TUN_MSG_PTR msg_control type. This type allows the caller to pass an array of XDP buffs to tuntap through ptr field of the tun_msg_control. Tap will build skb through those XDP buffers. This will avoid lots of indirect calls thus improves the icache utilization and allows to do XDP batched flushing when doing XDP redirection.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
