Large data segments are efficiently processed by setting up a plurality of Large Receive Segment Offload (LRO) queues within the computing system memory. The plurality of LRO queues are maintained concurrently so that a plurality of LRO contexts can be assembled simultaneously. A timer associated with each LRO queue prevents indefinite waiting for LRO segments to be completed.

Systems and methods for efficiently processing large data segments

Method and system for managing interrupts originating from multiple sources is provided. The method includes assigning interrupt sources to a group; notifying an adapter of interrupt groups; identifying each interrupt group; writing a first interrupt to an interrupt module, where the interrupt occurs from a first source of the multiple sources; monitoring for a second interrupt; suspending the second interrupt until the first interrupt is processed, if the second interrupt is requested from the first source; and processing the second interrupt, if the second interrupt occurs from a source other than the first source.

System and method for managing interrupts

A method for sending/receiving a TCP segment is provided. The sending process includes, determining if a TCP port can be offloaded; saving a host system's time stamp value; replacing a host system's time stamp value with a TCP offload engine ('TOE') adapter's time stamp value; and sending the TCP segment via the TOE adapter. The receiving process includes verifying if a TCP port is being offloaded by a host system to the TOE adpter; retrieving the host system's time stamp value; and inserting the host system's time stamp value in the received TCP segment before the forwarding the received TCP segment to the host system.
