PVRST+ support for Cumulus

[jbemmel]

I have a need for PVRST+ support on Cumulus. Per https://docs.nvidia.com/networking-ethernet-software/cumulus-linux-510/Layer-2/Ethernet-Bridging-VLANs/Traditional-Bridge-Mode/# this requires a "traditional Linux bridge" (along the lines of what we do for FRR)

How would we prefer to handle this?

Actually - never mind: https://docs.nvidia.com/networking-ethernet-software/cumulus-linux-56/Layer-2/Spanning-Tree-and-Rapid-Spanning-Tree/#pvrst-mode-for-a-vlan-aware-bridge

nv set bridge domain br_default stp mode pvrst
