test(e2e): live coverage for the switch cascade kernel datapath
Two switches cascaded through the link-owned veth pair, two c7200
routers per switch, real ICMP crossing both bridges: the pair is born
UP with exactly one end per switch bridge, a dot1q trunk cascade
carries two VLANs at once, the symmetric access/trunk mode flip on the
cascade ends isolates and revives a VLAN in place (asymmetric flips are
semantically broken — the access side egresses untagged into the far
trunk's native PVID), a delay filter lands as netem on both ends (one
per direction, RTT ~= 2x delay), suspend admin-downs both ends, and a
link delete/re-create retires the whole pair and mints a new one under
the new link id — zero host residue after the project goes.
