Hi Sasha,

I noticed the following problem a while ago - when the whole
duplicated guids and re-reading files mails were running,
but never had a chance to dig deeper.

Anyway, sometimes OpenSM 'sees' the same HCA ports twice.
For instance, when I run "opensm -V" on a two-port HCA with
a switch in between, OpenSM prints the following:

=======================================================================================================

Mellanox    : CA : 02 : ACT : 0002 :  0  : 2048 : 4x  : 2.5 : 0002c902000017a2 : 000b8cffff002037 (05)

The easiest way to reproduce it is to run it on a single HCA
with two ports connected directly.

It doesn't really disturbs anything (except for one of my tests
that counts some records), but anyway, any idea what's causing it?

thanks
