1. Keep the code for the normal (non-error) flow at the lowest indentation level. And use "goto drop" for all error handling. 2. Replace code that pads short Ethernet frames with a "__skb_pad" call. 3. Change "dev_kfree_skb" to "kfree_skb" in error handling code. "kfree_skb" is the correct function to call when dropping an skb due to an error. "dev_kfree_skb", which is an alias of "consume_skb", is for dropping skbs normally (not due to an error).

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.
