2018-07-03include/rdma/opa_addr.h: Fix an endianness issueBart Van Assche1-1/+1
IB_MULTICAST_LID_BASE is defined as follows: #define IB_MULTICAST_LID_BASE cpu_to_be16(0xC000) Hence use be16_to_cpu() to convert it to CPU endianness. Compile-tested only.

2017-12-22IB/SA: Check dlid before SA agent queries for ClassPortInfoVenkata Sandeep Dhanalakota1-0/+16
SA queries SM for class port info when there is a LID_CHANGE event. When a base lid is configured before fm is started ie when smlid is not yet assigned, SA handles the LID_CHANGE event and tries query SM with lid 0. This will cause an hang.

2017-10-04IB/core: Use __be32 for LIDs in opa_is_extended_lidDon Hiatt1-3/+3
The LIDs passed to opa_extended_lid are in __be32 format, change function signature accordingly.

2017-08-22IB/hfi1: Determine 9B/16B L2 header type based on Address handleDon Hiatt1-2/+2
When address handle attributes are initialized, the LIDs are transformed to be in the 32 bit LID space. When constructing the header, hfi1 driver will look at the LID to determine the packet header to be created.

2017-05-01IB/SA: Add OPA addr headerDoug Ledford1-0/+79
When importing the patch 57520751445b (IB/SA: Add OPA path record type), a new header file should have been added to the repo as part of the patch. However, as the patch didn't apply cleanly using git am, I instead used patch manually, and followed that up with git add -u, which misses new files. This adds the new file back in.
