Implementations

impl SriovCapability

pub fn parse(data: &[u8], offset: u16) -> Result<Self, VmError>

data should contain the SR-IOV capability structure starting at index 0.

pub fn vf_address(&self, pf: &PciAddress, vf_index: u16) -> Option<PciAddress>

Calculate the PCI address of a specific VF

pub fn cap_id() -> u16

Get the SR-IOV extended capability ID
