This patch simply renames struct ib_ah_attr to rdma_ah_attr as these fields specify attributes that are not necessarily specific to IB. Reviewed-by:

For OPA devices, SA will query the OPA classport info instead of the IB defined classport info. opa classport info exposes additional information and capabilities that are specific to OPA devices. Reviewed-by:

Both opa_vnic and the hfi driver use the same opa_classport_info definition. We will also have ib_sa capable of querying opa class port info and would need this definition. Move it to ib_mad.h for everyone to use. Signed-off-by:

SA will query and cache class port info as part of its initialization. SA will also invalidate and refresh the cache based on specific events. Callers such as IPoIB and CM can query the SA to get the classportinfo information. Apart from making the caller code much simpler, this change puts the onus on the SA to query and maintain classportinfo much like how it maitains the address handle to the SM. Reviewed-by:

The process_ecn intends to return a bool value. However it is doing so incorrectly by ANDing the fecn mask. The fecn bit is bit 31. Bool is not a native data type and is up to the compiler to implement how it sees fit. It is conceivable that this upper bit gets washed out. Fix by converting to a bool properly.

Ingress and egress port P_Key checking should always be performed for HFIs. This patch will enable ingress and egress P_Key checking when the port is initialized and will ignore the P_Key information sent by the FM in the port info structure which is meant to be used only by the switch.

Secure data is transferred across the link during verify cap. This includes Neighbor Guid, Type, and Port Number. This transfer is not guaranteed to complete until the 8051 firmware has completed processing of the state_complete frame. Move the consumption of this data from verify cap handling to link up handling to ensure the data is finalized. Additionally, do not notify the SM that the link is up until after this data is actually available. Reviewed-by:

The driver progress routines can call cond_resched() when a timeslice is exhausted and irqs are enabled. If the ULP had been holding a spin lock without disabling irqs and the post send directly called the progress routine, the cond_resched() could yield allowing another thread from the same ULP to deadlock on that same lock. Correct by replacing the current hfi1_do_send() calldown with a unique one for post send and adding an argument to hfi1_do_send() to indicate that the send engine is running in a thread. If the routine is not running in a thread, avoid calling cond_resched().

VL15 in the SC2VL table is used to indicate an invalid SC for the FM, however, internally the driver remaps SCs from VL15 to ILLEGAL_VL to prevent error counts. This mapping confuses the FM when performing a sweep, making it return a table mismatch error. Have SMA convert ILLEGAL_VL to VL15 entries for the SC2VL table queries. Reviewed-by:

A list of MGID/MLID pairs is built when doing a multicast attach. When the multicast detach is called, the list is searched, and regardless of the search outcome, the driver detach is called. If an MGID/MLID pair is not on the list, driver detach should not be called, and an error should be returned. Calling the driver without removing an MGID/MLID pair from the list can leave the core and driver out of sync.
