When an skb is received on a normal (non-Ethernet-emulating) PVC device, call skb_reset_mac_header before we pass it to upper layers. This is because normal PVC devices don't have header_ops, so any header we have would not be visible to upper layer code when sending, so the header shouldn't be visible to upper layer code when receiving, either.

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.
