/* On the SFC9000 family each port is associated with 1 PCI physical * function (PF) handled by sfc and a configurable number of virtual * functions (VFs) that may be handled by some other driver, often in * a VM guest. The queue pointer registers are mapped in both PF and * VF BARs such that an 8K region provides access to a single RX, TX * and event queue (collectively a Virtual Interface, VI or VNIC). * * The PF has access to all 1024 VIs while VFs are mapped to VIs * according to VI_BASE and VI_SCALE: VF i has access to VIs numbered * in range [VI_BASE + i << VI_SCALE, VI_BASE + i + 1 << VI_SCALE). * The number of VIs and the VI_SCALE value are configurable but must * be established at boot time by firmware.
