My bad, that was obviously suppose to include the MAC in question. So
one more time, in an attempt to set a static MAC table entry:
13 744 so:me:ma:cc
ovs-ofctl add-flow mybridge dl_dst=so:me:ma:cc,actions=output:13
I guess what I'm asking is, what should a static flow that says "MAC
so:me:ma:cc lives on port 13" look like? Again, goal is to have a
static table entry like behavior accomplished with this flow.
