Physical functions, virtual functions, and ports
For the IBM Integrated Network Adapter 100G, Network Express® and RoCE Express2 and RoCE Express3, each physical adapter port is associated with one physical function (PF) while virtual functions (VF) are associated with a parent PF and thus are indirectly associated with an adapter port. On IBM Z® and LinuxONE physical functions are used for hardware-related management and for special, sensitive
