Fix problem with uninitialized rx/tx deferred_start flags of the struct
rte_eth_rxconf/txconf by initializing with 0 value (deferred start of
the rx/tx queues is turned off). This setting allows device rx/tx
queues to start with rte_eth_dev_start().
CID 194999 (#1 of 1): Uninitialized scalar variable (UNINIT)
CID 195009 (#1 of 1): Uninitialized scalar variable (UNINIT)
Fixes: de3cfa2c9823 ("sched: initial import")

Is this Coverity ID? If so we have a defined format for it:
