There's no need to check min(budget, NUM_RX_DESC). At first budget (NAPI_POLL_WEIGHT = 64) is less then NUM_RX_DESC (256). And more important: Even in case of budget > NUM_RX_DESC we could safely continue processing descriptors as long as they are owned by the CPU. In addition replace rx_left with a normal counter variable, this allows to simplify the code. Last but not least there's no need any longer to pass the budget as an u32.

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.
