Wait for flow table update (+ minor cleanup) #7

Closed lantz closed 5 years ago

lantz commented 5 years ago

We assume the flow tables have been updated if a set of new flows (vlan, host MACs) are reported from ovs-ofctl.

send out gratuitous ARPs
wait for vlan and all host MACs in switch flow tables
add iputils-arping to test-dependencies.sh

@gizmoguy @anarkiwi My intent here (similar to the faucet end-to-end tests) was to check to make sure the new flows are present in each switch (and presumably if one is present then they all are.)

However, I am still seeing some sort of race condition occasionally where even though the flows seem to be present in all of the switches, the ping test is failing, which is unexpected.

So I may need to look into this a bit more.
