The tagging protocol driver contains logic to handle this, but the meta frames are optional functionality, and there are configurations when they aren't received (no PTP RX timestamping). Thus, the MAC DA from packets sent to the stack is not correct in all cases. Also, during testing it was found that the MAC DA patching procedure was incorrect. The investigation comes as a result of this discussion with Paolo: https://lore.kernel.org/netdev/f494387c8d55d9b1d5a3e88beedeeb448f2e6cc3.camel@redhat.com/ ==================== Signed-off-by: David S.
