There are scenarios in which the zerocopy path can get a kernel buffer instead of a net_iov and needs to copy it to the user, whether it is because of mis-steering or simply getting an skb with the linear part. In this case, grab a net_iov, copy into it and return it to the user as normally. At the moment the user doesn't get any indication whether there was a copy or not, which is left for follow up work.

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.
