Doug Brown f228549115 appletalk: Fix skb allocation size in loopback case 
[ Upstream commit 39935dccb21c60f9bbf1bb72d22ab6fd14ae7705 ]

If a DDP broadcast packet is sent out to a non-gateway target, it is
also looped back. There is a potential for the loopback device to have a
longer hardware header length than the original target route's device,
which can result in the skb not being created with enough room for the
loopback device's hardware header. This patch fixes the issue by
determining that a loopback will be necessary prior to allocating the
skb, and if so, ensuring the skb has enough room.

This was discovered while testing a new driver that creates a LocalTalk
network interface (LTALK_HLEN = 1). It caused an skb_under_panic.

README 

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.
