E. Bifurcated Endpoint Support for Independent Resets

Bifurcation allows running multiple PCI Express links from a single PCI Express slot. These PCI Express links require independent reset control. A common use case is PCIE_x8x8 dual endpoint mode topology in SmartNIC and other types of intelligent server add-in cards. In many of these systems, one endpoint is connected to the Root Port of a Host CPU on a server motherboard. The second endpoint is connected to the Root Port of a SoC Host on an add-in card.
