Both of those are/would be nice.  It would also be nice to be able
to accept and process certain types of packets on an interface, but
not actually forward them.  The classic case here is for things like
OSPF and PIM, protocols which usually only have meaning on the local
link.  This would be a global filter, but could be enabled/disabled
per interface if necessary.  This and the 'drop all packet (not just
protocol) FOO on this device' was being looked at by at least one
vendor last I heard.
