2017-08-24RDMA/(core, ulp): Convert register/unregister event handler to be voidLeon Romanovsky1-6/+1
The functions ib_register_event_handler() and ib_unregister_event_handler() always returned success and they can't fail. Let's convert those functions to be void, remove redundant checks and cleanup tons of goto statements.

2017-07-24RDMA: Remove useless MODULE_VERSIONLeon Romanovsky1-1/+0
All modules in drivers/infiniband defined and used MODULE_VERSION, which was pointless because the kernel version describes their state more accurate then those arbitrary numbers.

2017-05-01IB/core: Define 'ib' and 'roce' rdma_ah_attr typesDasaratharaman Chandramouli1-0/+1
rdma_ah_attr can now be either ib or roce allowing core components to use one type or the other and also to define attributes unique to a specific type. struct ib_ah is also initialized with the type when its first created. This ensures that calls such as modify_ah dont modify the type of the address handle attribute.

2017-04-20IB/opa-vnic: VNIC Ethernet Management Agent (VEMA) functionVishwanathapura, Niranjana1-0/+1078
OPA VEMA function interfaces with the Infiniband MAD stack to exchange the management information packets with the Ethernet Manager (EM). It interfaces with the OPA VNIC netdev function to SET/GET the management information. The information exchanged with the EM includes class port details, encapsulation configuration, various counters, unicast and multicast MAC list and the MAC table. It also supports sending traps to the EM.
