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):
