This looks really useful for debugging/tuning etc... what MIBs are
being dumped
here? The standard TCP and IPv4 MIBs?
Yes, this is a standard TCP MIB.
I take this back. These stats are a subset of the IP and TCP MIBs.
I'd like to get something out in 2.6.27/ofed-1.4 for support reasons
without opening the SNMP can of worms. So I'll define a standard struct
iw_protocol_counters and include the chelsio stats. Other providers can
expand if they care. I'll also add the core stuff to have sysfs.c
create the attribute files, one per stat and query the device to get the
values via a device get_iw_stats() call like you propose. The stats can
live in /sys/class/infiniband/$device/protocol_counters/iwarp/*.
How does that sound?
