Thanks for adding counters. They will be extremely helpful with our 
large scale cluster support. However, exporting them via debugfs will be 
useless in our production environments that do not have debugfs support 
built in the kernel. Can we expose these with the same mechanism as 
other IB/iWARP modules?

Thanks,
