More Information
Summary:Presented herein are systems and methods for packet processing in an information handling system that uses loopback processing. In one or more embodiments, buffer accounting is done with respect to the original ingress port for packets when using loopback processing. Such embodiments have several benefits, including but not limited to, mitigating or eliminating head-of-line (HoL) blocking of traffic and headroom (plus additional buffers which may need to be allocated for use before priority-based flow control is generated) provisioning for the loopback port. Embodiments may include additional features, such as handling anomalies (e.g., corruption) and reclaiming reserved buffers if corruption or delays occur.
