The "err" is always zero, so the following branch can never be executed:
if (err) {
ndev->stats.rx_dropped++;
kfree_skb(skb);
}
Therefore, the "if" statement can be removed.
Use "ndev->stats.rx_errors" to count "napi_build_skb()" failure

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.
