[PATCH net-next 0/3] net/mlx5: allocate doorbells from dma pools

[Tariq Toukan <tariqt@nvidia.com>]

Hi,

This series by Nimrod extends the mlx5 internal DMA pool infrastructure
to doorbell objects.

Doorbell allocations currently use a separate pgdir allocator. Moving
them to the common mlx5 DMA pool implementation keeps the same coherent
DMA allocation model while sharing the pool code used by mlx5_frag_buf.

The series first creates per-node doorbell pools, then switches doorbell
allocation to use them, and finally exposes their usage through debugfs.

Regards,
Tariq
