No particular reason. I just picked a name I thought reasonable, but I'm
fine with just VERSION on its own.
The one advantage of having DPDK in the title is that if one has a clone to
a directory called e.g. "temp", a quick "ls" will show the forgetful what
product it was that they cloned to a directory with such an unhelpful name.

Yes, but don't worry, I'm proposing a bit of an addition of sed and awk
to other makefile commands to compensate, though sadly not quite as
unintelligable to the masses as this. :-)
