This patch reverts earlier commitb13ba1b83f("macvlan: forbid L2 fowarding offload for macvtap"). The reason for reverting this is because the original patch no longer fixes what it previously did as the underlying structure has changed for macvtap. Specifically macvtap originally pulled packets directly off of the lowerdev. However in commit6acf54f1cf("macvtap: Add support of packet capture on macvtap device.") that code was changed and instead macvtap would listen directly on the macvtap device itself instead of the lower device. As such, the L2 forwarding offload should now be able to provide a performance advantage of skipping the checks on the lower dev while not introducing any sort of regression.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
