Roland, what's wrong with either plugging into the framework for IB statistics set by commit 7f624d023b5fb "RDMA/core: Add iWARP protocol statistics attributes in sysfs" for the IBTA defined statistics and have the vendor propeitary stats to be reported through the rdma netlink code, or having it all go through netlink (better to my taste).
Or.
we found that each stat will correspond to one file in sysfs tree therefore it will constitute a large number of files in ocrdma tree per port, situation will worsen if SRIOV and Multichannel comes into picture, On the other hand, with debugfs it is possible to have one file displaying multiple stats thus, drastically reducing the number of sysfs file entries. We had a discussion with Roland on this, and he gave us a go-ahead on this as well. However, if you still think we should honor IB-diag infra, we are open to populate IB-compliant stats into that framework as well along with debugfs entries.
