Subject: [PATCH v2 00/14] Introduce AMD Pensando RDMA driver

This patchset introduces an RDMA driver for the AMD Pensando adapter. 
An AMD Pensando Ethernet device with RDMA capabilities extends its 
functionality through an auxiliary device.

The first 6 patches of the series modify the ionic Ethernet driver 
to support the RDMA driver. The ionic RDMA driver implementation is 
split into the remaining 8 patches.

v1->v2
  - Removed netdev references from ionic RDMA driver
  - Moved to ionic_lif* instead of void* to convey information between
    aux devices and drivers.

Abhijit Gangurde (14):
  net: ionic: Create an auxiliary device for rdma driver
  net: ionic: Update LIF identity with additional RDMA capabilities
  net: ionic: Export the APIs from net driver to support device commands
  net: ionic: Provide RDMA reset support for the RDMA driver
  net: ionic: Provide interrupt allocation support for the RDMA driver
  net: ionic: Provide doorbell and CMB region information
  RDMA: Add IONIC to rdma_driver_id definition
  RDMA/ionic: Register auxiliary module for ionic ethernet adapter
  RDMA/ionic: Create device queues to support admin operations
  RDMA/ionic: Register device ops for control path
  RDMA/ionic: Register device ops for datapath
  RDMA/ionic: Register device ops for miscellaneous functionality
  RDMA/ionic: Implement device stats ops
  RDMA/ionic: Add Makefile/Kconfig to kernel build environment
