[openib-general] [PATCH 5/5] opensm: dump_lfts.sh compatible dumper for OpenSM

[Sasha Khapyorsky]

This is bonus - switch forwarding tables dump compatible with output
produced by dump_lfts.sh and which can be used as input for unicast
forwarding tables loader (with -R 'file' -U <file-name>). The dump file
name is 'opensm-lfts.sh' and will be generate if OSM_LOG_ROUTING
logging flag is set.
