Here is the summary with links:
  - [net-next,v6,1/7] queue_api: add support for fetching per queue DMA dev
    https://git.kernel.org/netdev/net-next/c/13d8e05adf9d
  - [net-next,v6,2/7] io_uring/zcrx: add support for custom DMA devices
    https://git.kernel.org/netdev/net-next/c/59b8b32ac8d4
  - [net-next,v6,3/7] net: devmem: get netdev DMA device via new API
    https://git.kernel.org/netdev/net-next/c/7c7e94603a76
  - [net-next,v6,4/7] net/mlx5e: add op for getting netdev DMA device
    https://git.kernel.org/netdev/net-next/c/f1debf1a2ef4
  - [net-next,v6,5/7] net: devmem: pull out dma_dev out of net_devmem_bind_dmabuf
    https://git.kernel.org/netdev/net-next/c/512c88fb0e88
  - [net-next,v6,6/7] net: devmem: pre-read requested rx queues during bind
    https://git.kernel.org/netdev/net-next/c/1b416902cd25
  - [net-next,v6,7/7] net: devmem: allow binding on rx queues with same DMA devices
    https://git.kernel.org/netdev/net-next/c/b8aab4bb9585

You are awesome, thank you!
