What would you suggest, add two additional LL QP types, or change something more fundamental in libibverbs and kernel ib core? We think we can get along quite well with the existing parameters in the current create QP. The current user-kernel interface is ok for these new QPs for post_send + post_recv, but unfortunately the libibverbs userspace calls don't match exactly how the LL queues are to be used. We would need something like the LL QP interface in libehca in libibverbs to keep that interface generic.
We didn't see a usage yet for LL QP in kernel, so maybe we should continue that discussion on [EMAIL PROTECTED] only. We could provide example code in libehca/samples if needed.
