Required Methods§

Source

fn new_with_name(name: &[u8], vnet_hdr: bool, multi_vq: bool) -> Result<Self>

Create a new tap interface named name, or open it if it already exists with the same parameters.

Set the vnet_hdr flag to true to allow offloading on this tap, which will add an extra 12 byte virtio net header to incoming frames. Offloading cannot be used if vnet_hdr is false. Set ‘multi_vq’ to true, if tap have multi virt queue pairs

Source

fn new(vnet_hdr: bool, multi_vq: bool) -> Result<Self>

Create a new tap interface. Set the vnet_hdr flag to true to allow offloading on this tap, which will add an extra 12 byte virtio net header to incoming frames. Offloading cannot be used if vnet_hdr is false. Set ‘multi_vq’ to true if tap has multi virt queue pairs.
