Expand description

Wakable version of TxRing

Implementations§

Source§

impl WakableTxRing

Source

pub unsafe fn send<S: Slab>( &mut self, packets: &mut S, wakeup: bool, ) -> Result<usize>

Enqueues packets to be sent by the kernel

§Safety

The crate::Umem that owns the packets being sent must outlive the AF_XDP socket

§Returns

The number of packets that were actually enqueued. This number can be lower than the requested num_packets if the ring doesn’t have sufficient capacity
