4 Configuring PCI Endpoint Using CONFIGFS
9 The PCI Endpoint Core exposes configfs entry (pci_ep) to configure the
10 PCI endpoint function and to bind the endpoint function
11 with the endpoint controller. (For introducing other mechanisms to
12 configure the PCI Endpoint Function refer to [1]).
17 The PCI Endpoint Core layer creates pci_ep directory in the mounted configfs
20 	mount -t configfs none /sys/kernel/config

42 	/sys/kernel/config/pci_ep/functions/
55 used to configure the standard configuration header of the endpoint function.
