This series of patches provides an ability to add VLANs to the bridge ports. This is similar to what can be found in most switches. The bridge port may have any number of VLANs added to it including vlan 0 priority tagged traffic. When vlans are added to the port, only traffic tagged with particular vlan will forwarded over this port. Additionally, vlan ids are added to FDB entries and become

Hi, Here are two, small feature changes I would like to submit to increase the usefulness of the multicast snooping of the bridge code. The first patch is an unaltered one I had submitted before, but since it got no feedback I'm resubmitting it here for net-next. With the recently added patch to disable snooping if there is no querier (b00589af + 248ba8ec05 + 8d50af4fb), it should be a safe

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

Changes since v9: * series re-ordering so make functionality more distinct. Basic vlan filtering is patches 1-4. Support for PVID/untagged vlans is patches 5 and 6. VLAN support for FDB/MDB is patches 7-11. Patch 12 is still additional egress policy. * Slight simplification to code that extracts the VID from skb. Since we now depend on the vlan module, at the time of input skb_tci is
