The packet is transmitted via $swp1, I don't understand how it can arrive at the egress of $swp2. > + > + sleep $((LOW_AGEING_TIME / 100 + 10)) &g...

tl;dr ===== This patchset adds a single bit to the skb to indicate that a packet encountered a layer 2 miss in the bridge and extends flower to match on this metadata. This is required for non-DF (Designated Forwarder) filtering in EVPN multi-homing which prevents decapsulated BUM packets from being forwarded multiple times to the same multi-homed host. Background ========== In a typical EVPN
