Hi,
Yes, it is still recommended to do a buildworld for userland tools, adding 'WITH_OFED=1' to /etc/make.conf.
Another way to go to install ibutils for instance:
cd /usr/src/contrib/ofed && make includes
cd /usr/src/contrib/ofed /usr.lib && make depend all install
cd /usr/src/contrib/ofed /usr.bin && make depend all install

For userland tools, is it still recommended to do a buildworld, or is a more targeted approach possible?
E.g., I'm thinking it might suffice to set WITH_OFED='yes' in src.conf and just rebuild select tools/libs. There appear to be things outside contrib/ofed and sys/modules that need to be rebuilt, but I wouldn't want to try and determine what they are on my own.
Thanks,
JB
