[dpdk-dev] [PATCH v1] net/ice: use rx/tx DMA iova instead of phys_addr which is deprecated

Haiyue Wang haiyue.wang at intel.com
Thu Jul 11 19:27:06 CEST 2019


The phys_addr concept is deprecated in rte_memzone, change it to access
iova member, and use the type 'rte_iova_t'.

Also rename the rx/tx_ring_phys_addr definitions to rx/tx_ring_dma that
matches the IOVA concept design.

Fixes: 50370662b727 ("net/ice: support device and queue ops")
