1 Intel IDPF device driver
2 ========================
7 This plugins provides native device support for Intel Infrastructure
8 Data Path Function (IDPF). The current IDPF is a driver specification
9 for future Intel Physical Function devices. IDPF defines communication
10 channel between Data Plane (DP) and Control Plane (CP).
15 - Driver requires MSI-X interrupt support, which is not supported by
16 uio_pci_generic driver, so vfio-pci needs to be used. On systems
17 without IOMMU vfio driver can still be used with recent kernels which
18 support no-iommu mode.
23 - This driver is still in experimental phase, and the corresponding device
26 - Current version only supports device initialization. Basic I/O function
27 will be supported in the next release.
35 Interfaces can be dynamically created by using following CLI:
39 create interface idpf 0000:4b:00.0 vport-num 1 rx-single 1 tx-single 1
40 set int state idpf-0/4b/0/0 up
42 vport-num: number of vport to be created. Each vport is related to one netdev.
43 rx-single: configure Rx queue mode, split queue mode by default.
44 tx-single: configure Tx queue mode, split queue mode by default.
49 Interface can be deleted with following CLI:
53 delete interface idpf <interface name>
58 Interface statistics can be displayed with
59 ``sh hardware-interface <if-name>`` command.
