1. A method comprising:
receiving, from a first computing device by a second computing device, a plurality of symbols across a set of lanes of a communication link between the first computing device and the second computing device in one or more clock cycles;
generating a physical layer extracted host physical address (eHPA) from the plurality of symbols received across the set of lanes of the communication link while performing operations at a physical layer of a receiving (Rx) protocol stack of the second computing device, wherein the eHPA is generated before other operations at other layers of the Rx protocol stack are performed;
using the eHPA to perform one or more operations for memory access before a normative message is formed by operations of the receiving protocol stack implemented in a communication interface of the second computing device.
