During the creation of the VLAN interface net device, the various device features and offloads are being set based on the parent device's features. The code initiates the basic, vlan and encapsulation features but doesn't address the MPLS features set and they remain blank. As a result, all device offloads that have significant performance effect are disabled for MPLS traffic going via this VLAN device such as checksumming and TSO. This patch makes sure that MPLS features are also set for the VLAN device based on the parent which will allow HW offloads of checksumming and TSO to be performed on MPLS tagged packets.

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.
