2020-05-27RDMA/cm: Add Enhanced Connection Establishment (ECE) bitsLeon Romanovsky1-0/+6
Extend REQ (request for communications), REP (reply to request for communication), rejected reason and SIDR_REP (service ID resolution response) structures with hardware vendor ID bits according to IBTA v1.4.

2020-01-25RDMA/cm: Remove CM message structsJason Gunthorpe1-1/+6
All accesses now use the new IBA acessor scheme, so delete the structs entirely and generate the structures from the schema file.

2020-01-25RDMA/cm: Add SET/GET implementations to hide IBA wire formatLeon Romanovsky1-0/+208
There is no separation between RDMA-CM wire format as it is declared in IBTA and kernel logic which implements needed support. Such situation causes to many mistakes in conversion between big-endian (wire format) and CPU format used by kernel. It also mixes RDMA core code with combination of uXX and beXX variables. The idea that all accesses to IBA definitions will go through special GET/SET macros to ensure that no conversion mistakes are made. The shifting and masking required to read the value is automatically deduced using the field offset description from the tables in the IBA specification. This starts with the CM MADs described in IBTA release 1.3 volume 1. To confirm that the new macros behave the same as the old accessors a self-test is included in this patch. Each macro replacing a straightforward struct field compile-time tests that the new field has the same offsetof() and width as the old field. For the fields with accessor functions a runtime test, the 'all ones' value is placed in a dummy message and read back in several ways to confirm that both approaches give identical results. Later patches in this series delete the self test. This creates a tested table of new field name, old field name(s) and some meta information like BE coding for the functions which will be used in the next patches.
