Expand description
Rust idiomatic bindings for the AF_XDP socket interface.
This library helps with creating suitable socket(s) from a memory allocation of chunks, sockets
for access to all four rings, binding to a specific (ifname, queue_id), and for creating the
memory mapping to interact with all these queues directly.
It does not interact with the packet filter / forwarding directly, nor any other aspect of
bpf. You can send packets but you can not receive them. Please use another library for bpf
and netlink interaction to configure the network device to route received frames to the RX
ring.
The entrypoint to the library is an instance of crate::Umem.
