Detailed Description

struct efx_vf - Back-end resource and protocol state for a PCI VF : The Efx NIC owning this VF : The PCI requester ID for this VF : The PCI name (formatted address) of this VF : Index of VF within its port and PF. : VFDI incoming request work item. Incoming USR_EV events are received by the NAPI handler, but must be handled by executing MCDI requests inside a work item. : VFDI incoming request DMA address (in VF's PCI address space). : Expected next incoming (from VF) VFDI_EV_TYPE member. : Expected next incoming (from VF) VFDI_EV_SEQ member. : Next VFDI_EV_SEQ member to reply to VF. Protected by : VFDI request queued to be processed or being processed. Receiving a VFDI request when is set is an error condition. : Incoming VFDI requests are DMA from the VF into this buffer. : Buffer table entries for this VF start at this index. : Receive filtering has been requested by the VF driver. : The flags sent in the VFDI_OP_INSERT_FILTER request. : VF relative qid for RX filter requested by VF. : Receive MAC filter ID. Only one filter per VF is supported. : Transmit MAC filtering mode. : Transmit MAC filter ID. : The MAC address and outer vlan tag of the VF. : VF DMA address of page for &struct vfdi_status updates. : Mutex protecting , , , and from simultaneous updates by the VM and consumption by efx_sriov_update_vf_addr() : Pointer to an array of guest pages for local addresses. : Number of entries in . : Array of guest pages backing evq0. : Number of entries in . : wait queue used by VFDI_OP_FINI_ALL_QUEUES handler to wait for flush completions. : Mutex for TX queue allocation. : Mask of initialized transmit queues. : Number of initialized transmit queues. : Mask of initialized receive queues. : Number of initialized receive queues. : Mask or receive queues that need to be flushed again due to flush failure. : Number of receive queues in . : Work item to schedule a VF reset.
