To more rapidly respond to Explicit Congestion Notifications, prescan the receive queue, and process FECNs, and BECNs first. When a UC, or RC packet containing a FECN, or BECN is found, immediately react to the ECN (either by returning a CNP, or adjusting the injection rate). Afterward, the packet will be processed normally.
