Subject: [PATCH net-next v2 0/5] net: sparx5: add support for port
mirroring
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.
