sxdp_shared_umem_fd field as you registered the UMEM on that
socket. These two sockets will now share one and the same UMEM.
In this case, it is possible to use the NIC's packet steering
capabilities to steer the packets to the right queue. This is not
possible in the previous example as there is only one queue shared
among sockets, so the NIC cannot do this steering as it can only steer
between queues.
There is no need to supply an XDP program like the one in the previous
case where sockets were bound to the same queue id and
device. Instead, use the NIC's packet steering capabilities to steer
the packets to the right queue. In the previous example, there is only
one queue shared among sockets, so the NIC cannot do this steering. It
can only steer between queues.
In libxdp (or libbpf prior to version 1.0), you need to use the
xsk_socket__create_shared() API as it takes a reference to a FILL ring
and a COMPLETION ring that will be created for you and bound to the
shared UMEM. You can use this function for all the sockets you create,
or you can use it for the second and following ones and use
xsk_socket__create() for the first one. Both methods yield the same
result.

Note that a UMEM can be shared between sockets on the same queue id
