This is a ML2 mechanism driver used by UTs in test_l2population.
|
|
This driver implements minimum requirements for L2pop mech driver.

As there are some agent-based mechanism drivers and OVS agent
|
|
mech driver is not the only one to support L2pop, it is useful to
|
|
test L2pop with multiple drivers like this to check the minimum
|

requirements.

of writing this. There's no need to keep this synced with the "real"
