➜  kernel git:(wip/leon-for-rc) git l --no-merges drivers/infiniband/hw/mana/
2145328515c8 RDMA/mana_ib: Use v2 version of cfg_rx_steer_req to enable RX coalescing
89d42b8c85b4 RDMA/mana_ib: Fix a bug when the PF indicates more entries for registering memory on first packet
563ca0e9eab8 RDMA/mana_ib: Prevent array underflow in mana_ib_create_qp_raw()
3574cfdca285 RDMA/mana: Remove redefinition of basic u64 type
0266a177631d RDMA/mana_ib: Add a driver for Microsoft Azure Network Adapter

It is different format from presented here. You added extra space before ":"
and there is double space in one of the titles.

Regarding aux, I see it, but what confuses me is proliferation of terms
and various calls: device, client, adapter. My expectation is to see
more uniform methodology where IB is represented as device.
