Commit86dd9868b8has several issues, but was accepted too soon before anyone could take a look. - Double free. dsa_slave_xmit() will free the skb if the xmit function returns NULL, but the skb is already freed by eth_skb_pad(). Use __skb_put_padto() to avoid that. - Unnecessary allocation. It has been done by DSA core since commita3b0b64797. - A u16 pointer points to skb data. It should be __be16 for network byte order. - Typo in comments. "numer" -> "number".

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.
