NVMe Over Fabric get error

[cocalele]

While testing NoF with softiwarp, the initiator get following error

# nvme discover -t rdma -a 127.0.0.1 -s 1023
Failed to write to /dev/nvme-fabrics: Connection refused

# dmesg
nvme nvme0: rdma_resolve_addr wait failed (-111).

The reason is becauses ofa_dev->alloc_mr is not implemented in function siw_device_create.

But I have no idea on how to implement this function :(

right. will look into it. have to understand & enable it for newer kernels.

map_mr_sg is also require by NoF but not implemented.

I opened a development branch 'dev-siw.mem_ext'. It implements mentioned memory management extensions. I tested with NVMeF (both initiator and target). Please treat that code as purely experimental - stability and performance will improve over time. It runs on kernels 4.8 and 4.10.
