macvlan/macvtap: Add support for L2 forwarding offloads with macvtap
This patch reverts earlier commit b13ba1b83f52 ("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 commit 6acf54f1cf0a ("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.
