cpumap still uses linked lists to store a list of skbs to pass to the stack. Now that we don't use listified Rx in favor of napi_gro_receive(), linked list is now an unneeded overhead. Inside the polling loop, we already have an array of skbs. Let's reuse it for skbs passed to cpumap (generic XDP) and keep there in case of XDP_PASS when a program is installed to the map itself. Don't list regular xdp_frames after converting them to skbs as well; store them in the mentioned array (but *before* generic skbs as the latters have lower priority) and call gro_receive_skb() for each array element after they're done.

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.
