[ Upstream commitafd5ba577c] XDP programs can release xdp_buff fragments when calling bpf_xdp_adjust_tail(). The driver currently assumes the number of fragments to be unchanged and may generate skb with wrong truesize or containing invalid frags. Fix the bug by generating skb according to xdp_buff after the XDP program runs.

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.
