This series adds support for port mirroring, and port mirroring stats, through tc matchall action FLOW_ACTION_MIRRED.
The hardware has three independent mirroring probes. Each probe can be configured with a separate set of filtering conditions that must be fulfilled before traffic is mirrored.
A mirror probe can have up to 64 source ports and a single monitor port. The direction of a mirror probe determines if rx or tx traffic is mirrored from the source port to the monitor port.
