Could you please give an example on what you mean with "accelerate the flow in HW". Many things could be accelerated and in many different ways. > 1.

It is possible to share the umem between AF_XDP sockets using xsk_socket__create_shared() function in libbpf. It works between netdevs, i.e. separate physical cards. But need the example first to be able to help you in a better way. /Magnus > Ratheesh. > > > > > > >
