Connect IceNIC and external module via a network tap

[Sabra Ossen]

Hi,

This receive path description mentions that we can connect external hardware modules to the IceNIC using network taps.

https://chipyard.readthedocs.io/en/stable/Generators/IceNet.html#receive-path 

From the packet buffer, the data can optionally go to a network tap, which examines the Ethernet header and select packets to be redirected from the NIC to external modules through one or more “tap out” interfaces. By default, there are no tap out interfaces, so the data will instead go directly to the writer, which writes the data to memory and then sends a completion to the controller.

Are there any examples on how to connect the IceNIC with an external module via a network tap?
