The only definitions for MAD data types are in ib_types.h, which is an opensm file. The libibumad interface is essentially useless without these data types. Add new header files to libibumad with basic MAD data types. The definitions and structures are based on those defined in the linux kernel. Only an initial framework is given, basically the values for various methods, attributes, etc. along with structure definitions for the common, rmpp, and vendor specific headers. Other data structures are left for future development. Signed-off-by: Sean Hefty <sean.hefty@intel.com> --- These patches were posted October 2010, but were never acted on. Reposting with updates based on the ib-mgmt git tree having been divided into separate git trees. include/infiniband/umad_types.h | 192 +++++++++++++++++++++++++++++++++++++++ 1 files changed, 192 insertions(+), 0 deletions(-) create mode 100755 include/infiniband/umad_types.h -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
