And confirmed, starting with a high packet number results in a very
short testbed run, 296 packets and then nothing, just as you surmised.
Sorry for raising the alarm falsely. Looks like I need to roll my own
build of wpa_supplicant as the ubuntu builds don't include the macsec
driver, haven't tes

Multiple map definition structures exist and user may have non-zero
fields in their definition that are not recognized by bpftool and
libbpf. The normal behavior is to then fail loading the map. Although
this is a good default behavior users may still want to load the map
for debugging or other rea
Sock map/hash introduce support for attaching programs to maps. To
date I have been doing this with custom tooling but this is less than
ideal as we shift to using bpftool as the single CLI for our BPF uses.
This patch adds new sub commands 'attach' and 'detach' to the 'prog'
command to attach prog
The first patch adds support for attaching programs to maps. This is
needed to support sock{map|hash} use from bpftool. Currently, I carry
around custom code to do this so doing it using standard bpftool will
be great.
The second patch adds a compat mode to ignore non-zero entries in
the map def.

Other than asoc pmtu sync from all transports, sctp_assoc_sync_pmtu
is also processing transport pmtu_pending by icmp packets. But it's
meaningless to use sctp_dst_mtu(t->dst) as new pmtu for a transport.
The right pmtu value should come from the icmp packet, and it would
be saved into transport->
