Is it really a must for this to be done by writing to sysfs? Couldn't
a trivial userspace app send a MAD locally to reset them?
We need it for diagnostic purposes.
The capability to reset counters locally on hosts helped us much in
large network/cluster diagnostics. Often, in case of fabric problems,
we can only access the counters locally.
A user space application is an option too, although I think it's nice
to have a 'built in' kernel feature.
