Struct WakableFillRing

Source 
pub struct WakableFillRing { /* private fields */ }
Expand description

The wakable version of FillRing, which requires that we notify the kernel when there are new buffers available to receive packets

Implementations§

Source§

impl WakableFillRing

Source

pub unsafe fn enqueue( &mut self, umem: &mut Umem, num_packets: usize, wakeup: bool, ) -> Result<usize>

The same as FillRing::enqueue, except the additional wakeup parameter determines if the kernel is actually informed of the new buffer(s) available to fill with data

§Safety

The Umem must outlive the AF_XDP socket
