[dpdk-dev] when create DMA space to NIC

[吕恩泳]

HI !

When create NIC tx_desc in eth_igb_tx_queue_setup(), tx_desc was allocated
by ring_dma_zone_reserve(). But when DMA speace was allocated by
EAL(memzone)?



eth_igb_tx_queue_setup()-->ring_dma_zone_reserve()-->memzone_lookup_thread_u
nsafe()-->mcfg->memzone[]



THANKS
