Abstract
A system for handling out-of-order frames may include one or more processors that enable receiving of an out-of-order frame via a network subsystem. The one or more processors may enable placing data of the out-of-order frame in a host memory, and managing information relating to one or more holes resulting from the out-of-order frame in a receive window. The one or more processors may enable setting a programmable limit with respect to a number of holes allowed in the receive window. The out-of-order frame is received via a TCP offload engine (TOE) of the network subsystem or a TCP-enabled Ethernet controller (TEEC) of the network subsystem. The network subsystem may not store the out-of-order frame on an onboard memory, and may not store one or more missing frames relating to the out-of-order frame. The network subsystem may include a network interface card (NIC).
