Description

The function of this block is to set the destination port meta data field for all packets. In the NIC every packet from an SFP+ connection is sent to the host. This is done by setting the destination port to be that of the host. When a packet is from the host the source port meta data is used to set the correct destination port for the SFP+ connection.
