This patchset implements a RDMA driver for Microsoft Azure Network
Adapter (MANA). In MANA, the RDMA device is modeled as an auxiliary device
to the Ethernet device.
The first 11 patches modify the MANA Ethernet driver to support RDMA driver.
The last patch implementes the RDMA driver.
The user-mode of the driver is being reviewed at:
https://github.com/linux-rdma/rdma-core/pull/1177
Ajay Sharma (3):
net: mana: Set the DMA device max segment size
net: mana: Define and process GDMA response code
GDMA_STATUS_MORE_ENTRIES
net: mana: Define data structures for protection domain and memory
registration
Long Li (9):
net: mana: Add support for auxiliary device
net: mana: Record the physical address for doorbell page region
net: mana: Handle vport sharing between devices
net: mana: Export Work Queue functions for use by RDMA driver
net: mana: Record port number in netdev
net: mana: Move header files to a common location
net: mana: Define max values for SGL entries
net: mana: Define data structures for allocating doorbell page from
GDMA
RDMA/mana_ib: Add a driver for Microsoft Azure Network Adapter
