TODO: - The definitions of SADB_* in sys/net/pfkeyv2.h are still different from RFC2407/IANA assignment because of binary compatibility issue. It should be fixed under 5-CURRENT. - ip6po_m member of struct ip6_pktopts is no longer used. But, it is still there because of binary compatibility issue. It should be removed under 5-CURRENT.

.Sh IMPLEMENTATION NOTES
When built without
.Xr kvm 3
support, the information displayed by
.Nm
is more limited.
This support is recommended for debugging purposes.
It requires superuser privilege if used to inspect a running kernel.
.Pp
When run without using
.Xr kvm 3
support,
.Nm
may print multicast MAC addresses twice if they are
referenced by a layer 3 protocol.
.Pp
When run with
.Xr kvm 3
support,
the names of all interfaces configured in the system will be
printed in the first column of output, even if no multicast
addresses are configured on those interfaces.
