However, because it is not in > rte_eth_dev_data structure, the array is not getting initialized for > secondary processes - neither is it getting appropriately resized if the > number of RX/TX queues changes. This causes crashes in secondary > processes as they dereference a null pointer in struct rte_eth_dev. > > This patch fixes this by introducing an upper-bound on the number of > queues per port that can be configured, and then uses this to make the > array statically sized, thereby avoiding the crashes. > > Signed-off-by: Bruce Richardson <bruce.richardson at intel.com>
