Hi Ruslan,

Yes, I can reproduce this issue. The patch is still necessary, however,=20
it does not resolve the if_ng issue because if_ng is a virtual interface
that is not really associated with any physical nic. The physical NIC is
where all of the entries (including the proxied entries) are kept.

Let me put some thoughts into how to resolve this problem.

>=20

Right, doing so allow the networking kernel to find the correct physical
NIC.
