Mainline Linux tree for various devices, only for fun :)

Move the skb_headroom check out of fr_hard_header and into pvc_xmit. This has two benefits: 1. Originally we only do this check for skbs sent by users on Ethernet- emulating PVC devices. After the change we do this check for skbs sent on normal PVC devices, too. (Also add a comment to make it clear that this is only a protection against upper layers that don't take dev->needed_headroom into account. Such upper layers should be rare and I believe they should be fixed.) 2. After the change we can simplify the parameter list of fr_hard_header. We no longer need to use a pointer to pointers (skb_p) because we no longer need to replace the skb inside fr_hard_header.

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.
