1. A network interface controller (NIC) chip that allows a host computer to communicate with a network, the NIC chip comprising:
a command queue to store a command issued via a host interface, the command queue comprising two independent sets of queues for initiator commands including a first queue for PUT commands and a second queue for GET commands;
a message chopping unit (MCU) to determine a type of the command and a Response Packet Length (RspPktLen) length of a response of the command;
a traffic shaping logic block to:
in response to the command being a data request, determine that the RspPktLen length of the response is exceeding a threshold, and
increment an Outstanding Packets Active (OrdPktActive) count in response to the command being constructed, decrement the OrdPktActive count in response to the response being processed, and stall, by an outbound transfer engine of the NIC chip, a generation of the command in response to the RspPktLen length exceeding the threshold; and
a traffic shaper of the outbound transfer engine to:
in response to determining the OrdPktActive count and the RspPktLen length, determine that the response for the command being the data request is within the threshold; and
select an output buffer for forwarding.
