ABSTRACT:
Method and system for processing read requests sent by a network interface device to a host system is provided. The method includes sending staggered read requests within a programmable time interval (“T”), wherein a transmit direct memory access (DMA) module sends more than one read request to the host system within the time interval T; placing data received from the host system in response to the read requests in independent slots of a transmit buffer; and unloading the transmit buffer slots based on an unload command, wherein the unload command is based on a mapping of read requests corresponding to transmit buffer slot locations where data from the host system is stored, and data is sent from the transmit buffer to a network device in the same order as the read requests that are sent from the network interface device to host system.
