Abstract: A computer implemented method and data processing system for the detection and recovery of a network interface card TCP acceleration offload failure. Responsive to a failure to receive an acknowledgement of a transmission control protocol segment containing a request for a transmission control protocol offload function in a network interface card, the transmission control protocol segment is retransmitted without the request for a transmission control protocol offload function. When an acknowledgement of the retransmitted transmission control protocol segment without the request for a transmission control protocol offload function is received, a counter is incremented which indicates a failure of the transmission control protocol offload function. Responsive to the counter exceeding a predefined number of allowed failures, all requests to the transmission control protocol offload function for the network interface card are stopped.
