IB/{rdmavt, hfi1, qib}: Remove get_card_name() downcall

2018-01-05T18:34:55Z

rdmavt has a down call to client drivers to retrieve a crafted card name. This name should be the IB defined name. Rather than craft the name each time it is needed, simply retrieve the IB allocated name from the IB device. Update the function name to reflect its application. Clean up driver code to match this change. Reviewed-by: Mike Marciniszyn Signed-off-by: Michael J. Ruhl Signed-off-by: Dennis Dalessandro Signed-off-by: Doug Ledford

IB/{rdmavt, hfi1, qib}: Self determine driver name

2018-01-05T18:34:55Z

Currently the HFI and QIB drivers allow the IB core to assign a unit number to the driver name string. If multiple devices exist in a system, there is a possibility that the device unit number and the IB core number will be mismatched. Fix by using the driver defined unit number to generate the device name. Reviewed-by: Mike Marciniszyn Signed-off-by: Michael J. Ruhl Signed-off-by: Dennis Dalessandro Signed-off-by: Doug Ledford

IB/hfi1: Send MAD traps until repressed

2017-07-31T19:17:55Z

A trap should be sent to the FM until the FM sends a repress message. This is in line with the IBTA 13.4.9. Add the ability to resend traps until a repress message is received.

IB/{rdmavt, qib, hfi1}: Remove gfp flags argument

2017-07-18T01:21:23Z

The caller to the driver marks GFP_NOIO allocations with help of memalloc_noio-* calls now. This makes redundant to pass down to the driver gfp flags, which can be GFP_KERNEL only. The patch removes the gfp flags argument and updates all driver paths. Signed-off-by: Leon Romanovsky Signed-off-by: Leon Romanovsky Acked-by: Dennis Dalessandro Signed-off-by: Doug Ledford

IB/rdmavt: Compress adjacent SGEs in rvt_lkey_ok()

2017-06-27T20:56:33Z

SGEs that are contiguous needlessly consume driver dependent TX resources. The lkey validation logic is enhanced to compress the SGE that ends up in the send wqe when consecutive addresses are detected. The lkey validation API used to return 1 (success) or 0 (fail). The return value is now an -errno, 0 (compressed), or 1 (uncompressed). A additional argument is added to pass the last SQE for the compression. Loopback callers always pass a NULL to last_sge since the optimization is of little benefit in that situation.

IB/core: Rename struct ib_ah_attr to rdma_ah_attr

2017-05-01T18:32:43Z

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