Hi,

When modeling pipelines of processing nodes that communicate
through streaming interfaces (e.g AXI-Stream), some of these
nodes send packets while others may just stream unpacketized data.

The purpose of this series is to add an end-of-packet flag, e.g
what AXI-Stream calls tlast. This is in preparation for modeling
future nodes that may use huge packets that we wouldn't be able
to buffer and also to handle nodes that don't use packets.

Along the way I fixed a few things in the petalinux-ml605 eth setup.

Cheers,
Edgar
