Currently, we don't add headroom to the handle in i40e_zca_free, i40e_alloc_buffer_slow_zc and i40e_alloc_buffer_zc. The addition of the headroom to the handle was removed in commit2f86c806a8("i40e: modify driver for handling offsets"), which will break things when headroom is non-zero. This patch fixes this and uses xsk_umem_adjust_offset to add it appropritely based on the mode being run.

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.
