This patch set is aiming to automatically find the optimal
queue <-> irq multi-queue assignments in storage ULPs (demonstrated
on nvme-rdma) based on the underlying rdma device irq affinity
settings.
First two patches modify mlx5 core driver to use generic API
to allocate array of irq vectors with automatic affinity
settings instead of open-coding exactly what it does (and
slightly worse).
Then, in order to obtain an affinity map for a given completion
vector, we expose a new RDMA core API, and implement it in mlx5.
The third part is addition of a rdma-based queue mapping helper
to blk-mq that maps the tagset hctx's according to the device
affinity mappings.
I'd happily convert some more drivers, but I'll need volunteers
to test as I don't have access to any other devices.
I'll test cxgb4 if you convert it. :)
