Struct RxRing

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

Ring from which we can dequeue packets that have been filled by the kernel

Implementations§

Source§

impl RxRing

Source

pub unsafe fn recv(&mut self, umem: &Umem, packets: &mut HeapSlab) -> usize

Pops packets that have finished receiving

The number of packets returned will be the minimum of the number of packets actually available in the ring, and the remaining capacity in the slab

§Returns

The number of actual packets that were pushed to the slab

§Safety

The packets returned in the slab must not outlive the Umem
