If I understand this correctly, each ssows_get_work() call will wait up to N
ns, where N is the dequeue_timeout_ns value supplied to
ssovf_mbox_getwork_tmo_set() in ssovf_configure().
So in ssows_deq_timeout, the wait time is (worst case) timeout_ticks * (N * (ns
to tick conversion factor)) ticks, which depends on the user-supplied N at
eventdev configuration time.
Perhaps in ssovf_configure, if the RTE_EVENT_DEV_CFG_PER_DEQUEUE_TIMEOUT flag
is used, the getwork timeout should be set to 1 tick?
Thanks,
Gage
