We want to expose to userspace (and hook to in libibverbs) the ability to
block multicast loopback for a QP. This will enable userspace applications
to get better performance. Ron's patchset does it by exposing it in ib_uverbs,
then posting the command from libibverbs, and going through limlx4.
Is it possible to do it in a better way?
What is the status of XRC patches? AFAIK they were submitted at least six months
ago, but still not merged. Is uverbs/libibverbs/libmlx4 freezed until they will be merged?
