MANA is a network interface card to be used in the Azure cloud environment.
MANA provides safe access to user memory through memory registration. It has
IOMMU built into the hardware.

MANA uses IB verbs and RDMA layer to configure hardware resources. It
requires the corresponding RDMA kernel-mode and user-mode drivers.

The MANA RDMA kernel-mode driver is being reviewed at:
https://patchwork.kernel.org/project/netdevbpf/list/?series=678843&state=*

The MANA RDMA user-mode driver is being reviewed at:
https://github.com/linux-rdma/rdma-core/pull/1177
