Align ravb_poll() with the documentation in `Documentation/networking/kapi.rst` and `Documentation/networking/napi.rst`. The documentation says that we should prefer napi_complete_done() over napi_complete(), and using the former allows us to properly support busy polling. We should ensure that napi_complete_done() is only called if the work budget has not been exhausted, and we should only re-arm interrupts if it returns true.

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.
