dpddelay just controls how often we send a DPD probe.
dpdtimeout just controls how long we allow missing DPD probes until we
declare the connection dead.
dpdaction determines the action executed upon reaching dpdtimeout.
if either dpddelay or dpdtimeout is set, but not the other, the other
defaults to 30 seconds for dpddelay and 120 seconds for dpdtimeout.
