[openib-general][RFC][PATCH] core/sysfs.c: ability to reset port counters

Why do you need this possibility?  Having counters reset locally is
going to confuse any performance manager running on the fabric that
might be reading the counters remotely.

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?
