The brctl Ethernet switch runs a per-port uBridge relay, so it can host
the mark filter and packet filters like any uBridge-backed node. Add
ethernet_switch to _MARKER_CAPABLE_TYPES and _get_filter_node, narrow the
UDPLink.update() NIO-PUT skip down to the Dynamips-hosted ethernet_hub,
and expose the matching compute endpoints: PUT nio (filter/marker
reapply) plus the per-marker toggle/pause/resume/delete/rebuild routes.
The ethernet_hub keeps its exclusion: its routes still wire into the
Dynamips hub, which has no uBridge of its own.
Replace the builtin EthernetSwitch stub with a Linux kernel bridge backed
by uBridge's brctl module. Each switch node creates one kernel bridge
(gns3br{N}) with VLAN filtering; each port is a persistent TAP enslaved to
the bridge, relayed by a per-port uBridge bridge (nio_tap <-> nio_udp).
- Access/dot1q/qinq port modes translated to brctl vlan primitives
- Compute router repointed from Dynamips to Builtin manager
- Tests updated: 21 router-level tests + 215 surrounding tests pass
- Real-kernel e2e verified: access 100 PVID untagged, dot1q trunk
VIDs 1-4094 + native 1, qinq 802.1ad proto + 200 PVID
Ethertype 0x9100/0x9200 handling and port-count guard relaxation are
deferred pending resolution.
