Beschreibung
Zusammenfassung:	Examples described herein relate to a network interface device that performs: offloading processing of fragments of a packet to an accelerator; processing non-fragmented packets; and prioritizing dropping of fragments of the packet over dropping of non-fragmented packets. Offloading processing of fragments of the packet to the accelerator can include: the accelerator performing: reassembling the fragments of the packet into a first reassembly packet; and based on congestion associated with at least one of the fragments of the packet of the first reassembly packet: dropping fragments of the first reassembly packet associated with one or more flows; halting reassembly of the first reassembly packet; and forwarding a second packet to a host system, wherein the second packet indicates that congestion occurred, identifies one or more impacted flows, and indicates a number of dropped packet fragments.
