This file describes the i40evf Linux* Base Driver for the Intel(R) XL710
|
||||
X710 Virtual Function.
|
||||
|
||||
The i40evf driver supports XL710 and X710 virtual function devices that
|
||||
can only be activated on kernels with CONFIG_PCI_IOV enabled.
|
||||
|
||||
The guest OS loading the i40evf driver must support MSI-X interrupts.
|
||||
|
||||

/* Description:
|
||||
* This header file describes the VF-PF communication protocol used
|
||||
* by the various i40e drivers.
|
||||
*
|
||||
* Admin queue buffer usage:
|
||||
* desc->opcode is always i40e_aqc_opc_send_msg_to_pf
|
||||
* flags, retval, datalen, and data addr are all used normally.
|
||||
* Firmware copies the cookie fields when sending messages between the PF and
|
||||
* VF, but uses all other fields internally. Due to this limitation, we
|
||||
* must send all messages as "indirect", i.e. using an external buffer.
|
||||
*
|
||||
* All the vsi indexes are relative to the VF. Each VF can have maximum of
|
||||
* three VSIs. All the queue indexes are relative to the VSI. Each VF can
|
||||
* have a maximum of sixteen queues for all of its VSIs.
|
||||
*
|
||||
* The PF is required to return a status code in v_retval for all messages
|
||||
* except RESET_VF, which does not require any response. The return value is of
|
||||
* i40e_status_code type, defined in the i40e_type.h.
|
||||
*
|
||||
* In general, VF driver initialization should roughly follow the order of these
|
||||
* opcodes. The VF driver must first validate the API version of the PF driver,
|
||||
* then request a reset, then get resources, then configure queues and
|
||||
* interrupts. After these operations are complete, the VF driver may start
|
||||
* its queues, optionally add MAC and VLAN filters, and process traffic.
