Re: [PATCH rdma-next 00/13] Add RDMA inline crypto support

Today, if one would like to run both features using a capable device then
the PI will be offloaded (no SW fallback) and the Encryption will be using
SW fallback.

It's not just running both - it's offering both as currently registering
these fatures is mutally incompatible.

For sure we would like to offer both, but as mentioned before, this will require blk layer instrumentation and ib_core instrumentation to some pipeline_mr or something like that.

Can you explain what is needed in the block layer that prevents queueing
a request that has PI and crypto ctx?

As for the rdma portion, I don't know enough if this is something
that is supported by the HW and lacks a SW interface, or inherently
unsupported in HW...
