Bring over all the work from the /tmp/ib-hw-detect branch. In addition to my design and testing, it was conceptually approved by Gil, Gleb, Pasha, Brad, and Galen. Functionally [probably somewhat lightly] tested by Galen. We may still have to shake out some bugs during the next few months, but it seems to be working for all the cases that I can throw at it. Here's a summary of the changes from that branch: * Move MCA parameter registration to a new file (btl_openib_mca.c): * Properly check the retun status of registering MCA params * Check for valid values of MCA parameters * Make help strings better * Otherwise, the only default value of an MCA param that was changed was max_btls; it went from 4 to -1 (meaning: use all available) * Properly prototyped internal functions in _component.c * Made a bunch of functions static that didn't need to be public * Renamed to remove "mca_" prefix from static functions * Call new MCA param registration function * Call new INI file read/lookup/finalize functions * Updated a bunch of macros to be "BTL_" instead of "ORTE_" * Be a little more consistent with return values * Handle -1 for the max_btls MCA param * Fixed a free() that should have been an OBJ_RELEASE() * Some re-indenting * Added INI-file parsing * New flex file: btl_openib_ini.l * New default HCA params .ini file (probably to be expanded over time by other HCA vendors) * Added more show_help messages for parsing problems * Read in INI files and cache the values for later lookup * When component opens an HCA, lookup to see if any corresponding values were found in the INI files (ID'ed by the HCA vendor_id and vendor_part_id) * Added btl_openib_verbose MCA param that shows what the INI-file stuff does (e.g., shows which MTU your HCA ends up using) * Added btl_openib_hca_param_files as a colon-delimited list of INI files to check for values during startup (in order, left-to-right, just like the MCA base directory param). * MTU is currently the only value supported in this framework. * It is not a fatal error if we don't find params for the HCA in the INI file(s). Instead, just print a warning. New MCA param btl_openib_warn_no_hca_params_found can be used to disable printing the warning. * Add MTU to peer negotiation when making a connection * Exchange maximum MTU; select the lesser of the two This commit was SVN r11182.
