[ Upstream commit 2ac8af0967aaa2b67cb382727e784900d2f4d0da ]
The check for src mac address in ibmveth_is_packet_unsupported is wrong. Commit 6f2275433a2f wanted to shut down messages for loopback packets, but now suppresses bridged frames, which are accepted by the hypervisor otherwise bridging won't work at all.
