Version 4.4.0 and newer of the Dolphin software stack includes a legacy TCP/IP driver (IPoPCIe) for the PCI Express interconnect. Most applications should NOT use this driver as SuperSockets normally will give much lower latency and higher throughput. However, some applications and services are not supported by SuperSockets and needs to use the TCP/IP driver to benefit from PCI Express. The following applications are known to benefit from the TCP/IP driver:
Applications that does not need low latency, high throughput.
Windows Kernel services and drivers (SuperSockets only support user space applications)
