No management port is revenue port, and will kill your flow export, if
flow export is supported directly from the NPU. Because if it works,
it means NPU has to _punt_ the traffic to control-plane, to export it.
Where as if NPU supports exporting off the NPU, then exporting from
non-revenue ports can be done without touching control-plane or
stealing punt capacity.
If flow is exported by the RE, it's much less important.

I would personally not use any RE attached ETH port for any purpose.
However I'd happily use ASR9k CMP port or Cisco 8k BMC port for
out-of-band.
