Long Li says:

====================
Introduce Microsoft Azure Network Adapter (MANA) RDMA driver [netdev prep]

The first 11 patches which modify the MANA Ethernet driver to support
RDMA driver.

* 'mana-shared-6.2' of https://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma:
  net: mana: Define data structures for protection domain and memory registration
  net: mana: Define data structures for allocating doorbell page from GDMA
  net: mana: Define and process GDMA response code GDMA_STATUS_MORE_ENTRIES
  net: mana: Define max values for SGL entries
  net: mana: Move header files to a common location
  net: mana: Record port number in netdev
  net: mana: Export Work Queue functions for use by RDMA driver
  net: mana: Set the DMA device max segment size
  net: mana: Handle vport sharing between devices
  net: mana: Record the physical address for doorbell page region
  net: mana: Add support for auxiliary device
