But packets can "appear;->" to be coming from an aliased IP. Also
packets could be addresses to a virtual address. Could it be
defined as a link from that perspective? And it seems to make sense to
keep count of such packets.
Maybe it is logical to have a physical ifindex + counters as well
as virtual ones (i,e ifindex+counter). I dont think current SNMP standards
support that; but then i am no expert there.

Do you mean, netdevice? ;-> I have seen interface being abused to mean a
lot of things (eg the packet munging, such as routing, is refered by some
people as "interface").
