Abstract:
1. A method for providing per-port maximum packet payload sizes in an Input/Output (I/O) interconnect having a midpoint device, wherein the midpoint device has a plurality of ports, the method comprising: receiving a request to initiate a session between a device on a first port of the midpoint device and a device on a second port of the midpoint device; retrieving a maximum payload size for the device on the first port by accessing a first entry in a data structure, the first entry corresponding to the first port; retrieving a maximum payload size for the device on the second port by accessing a second entry in the data structure, the second entry corresponding to the second port; and establishing a session between the device on the first port and the device on the second port, using the maximum payload size for the device on the first port and the maximum payload size for the device on the second port, independently of support of the maximum payload size on other ports; wherein the establishing a session includes:
