With the introduction of bpf_link in xsk's libbpf part, there's no further need for explicit unload of prog on xdpsock's termination. When process dies, the bpf_link's refcount will be decremented and resources will be unloaded/freed under the hood in case when there are no more active users. While at it, don't dump stats on error path. Signed-off-by: Maciej Fijalkowski <maciej.fijalkowski@intel.com> ---Can we also use it from selftests prog so we have a test that is run there using this? Looks like xdpxceiver.c could do the link step as well?
Yes! Good point! Björn
