# UDP Ports --------------------------------------------------------------------
# mode `raw` vs `streamer` mode:
# The streamer mode is a convenience wrapper around a `raw` UDP port. A raw UDP
# port receives and requires the full UDP header information without filtering.
# In addition, when transmitting packets, it's required to make sure the user
# can burst a full packet without issuing a stall.
# The `streamer` mode on the other hand, allows a port to be specified to
# receive/transmit on. There is also a FIFO between the raw port and the
# streamer port. This means the user is not required to be able to burst packet
# into the core. But a limitation of this is that the user relinquishes
# control of transmitted UDP packet sizes.
