[openib-general] [opensm] the default behavior of the openSM causes problems (configure the PKey table)

[Dotan Barak]

Hi.

I noticed that the behavior of the openSM was changed in the latest driver:

in the past, every HCA was configured (by the FW) with 0xffff in the first entry.
today, the PKey table is being configured by the openSM: the first entry 
is being set to 0x7fff (except for the host that the SM is being executed from)

This behavior is very problemtic because not all of the users would like 
to change the default PKey table (for example: MPI users). 
Users that will try to use OFED 1.1 (in the same way they used OFED 1.0) will 
get unexplained failures, because the connectivity because the nodes will be broken.
(even the perfquery started to fail after executing the SM)


I think that the default behavior of the openSM should be: not to change the 
PKey table, unless the user provided a PKey table policy file.

Here are the props of the machines
