Hi Suri,
You can send a PMA PortCounters MAD either using "process local" or to
the device using its LID.

Hal:
The way I gather port stats locally on my device is by doing a "cat" on the
"/sys/class/Infiniband/mysw/port/0/counters" file. As Roland mentioned this
is limited to port0 counters on a switch.
If I need stats for port#N I need to expand this by providing more class
attributes and getting to

[SS] That's a bummer, so don't we need to create as many file descriptors as
the number of physical ports on a switch, so that we can

A switch only has one port through which all MADs are processed (switch
port 0 (either base or enhanced))

Hi:
For a switch only one port_priv object is created in mad.c. As a result, it
appears like the process_mad function is always called with a port number of
zero.
And the return path is always filled with zero as well (in smi.c). Should
not this be the physical port number from which the mad pac
