[pve-devel] [PATCH network] api: sdn: fix null vmid for tap/veth ports on bridges api call

[Gabriel Goller]

When using an interface without a firewall on a VM or container, it
results in tap<vmid>i<index> or veth<vmid>i<index> bridge ports.
Previously, a single regex with multiple options caused incorrect
capture group variables, $1 and $2 would always refer to the first group
(fwpr) even if we matched on e.g. `veth`. Split into separate matches.
