Revert "macvlan : fix checksums error when we are in bridge mode"
This reverts commit 12a2856b . The commit above doesn't appear to be necessary any more as the checksums appear to be correctly computed/validated. Additionally the above commit breaks kvm configurations where one VM is using a device that support checksum offload (virtio) and the other VM does not. In this case, packets leaving virtio device will have CHECKSUM_PARTIAL set. The packets is forwarded to a macvtap that has offload features turned off. Since we use CHECKSUM_UNNECESSARY, the host does does not update the checksum and thus a bad checksum is passed up to the guest.
