This series adds support for netmap VALE and pipe ports, makes a few
changes to the tests to cope with the fact these ports don't have a MAC
address and adds a script to test them as part of "make check".
Apart from being an easy way to test the netmap code without needing
physical interfaces, the VALE/pipe ports make it easy to inject a lot
of traffic for local testing. The netmap docs say 100Mpps is possible
through a pipe, I haven't seen that but I do get >20Mpps. Also VALE
switches can be created dynamically so it's easy to create relatively
complex test networks.
VALE should obviously also provide decent VM-to-VM speeds, but I've
not tried that.
To open a VALE port use a pktio name with the name "valeXXX:YYY" where
XXX is an arbitrary name for the switch (which will be created if it
doesn't exist) and YYY is the port on that switch. For example names
"valea:0" and "valea:1" give you two ports on the same switch.
To open a pipe use names e.g. "valea:0{0" for master and "valea:0}0"
for slave.
