[PATCH vhost v4 00/11] virtio core prepares for AF_XDP
...| 43% | 771670
Before achieving the function of Virtio-Net, we also have to let virtio core
support these features:
1. virtio core support premapped
2. virtio core support reset per-queue
3. introduce DMA APIs to virtio core
Please review.
Thanks.
v4:
1. rename map_inter to dma_map_internal
2. fix: Excess function parameter 'vq' description in 'virtqueue_dma_dev'
v3:
1. add map_inter to struct desc state to reocrd whether virtio core do dma map
v2:
1. based on sgs[0]->dma_address to judgment is premapped
2. based on extra.addr to judgment to do unmap for no-in...

I prefer a full name. E.g. "dma_map_internal". Eschew abbreviation.
