This patchset add Kunpeng930 DMA devices, and also include two patch
used to enhance HiSilicon DMA PMD.

Chengwen Feng (5):
  dma/hisilicon: support Kunpeng930 DMA devices
  dma/hisilicon: support handles errors with Kunpeng930 DMA
  dma/hisilicon: support dump Kunpeng930 DMA registers
  dma/hisilicon: add queue full statistics
  dma/hisilicon: use EAL API to generate dmadev name

The Kunpeng930 DMA devices have the same PCI device id with Kunpeng920,
but with different PCI revision and register layout. This patch
introduces the basic initialization for Kunpeng930 DMA devices.

* [PATCH 5/5] dma/hisilicon: use EAL API to generate dmadev name

For DMA device 0000:7d:0.0, the original generated dmadev name starts
with the "7d:0.0", which is not expected.
This patch uses rte_pci_device_name API to generates the dmadev name.
