This is for a different node where I can get ibnetdiscover to run, but the results are:

vendid=0x2c9
devid=0x5a44
sysimgguid=0x2c90107fc5be3
caguid=0x2c90107fc5be0
Ca      2 "H-0002c90107fc5be0"          # "MT23108 InfiniHost Mellanox Technologies"
[1](2c90107fc5be1)      "S-0002c9010b08fb60"[24]                # lid 2 lmc 0 "MT47396 Infiniscale-III Mellanox Technologies" lid 3 4xSDR

The HCA driver simply reports back whatever has been set in its local node_desc field, which is settable by writing to a file:

echo Goofy > /sys/class/infiniband/mthca0/node_desc

new outout is:

vendid=0x2c9
devid=0x5a44
sysimgguid=0x2c90107fc5be3
caguid=0x2c90107fc5be0
Ca      2 "H-0002c90107fc5be0"          # "Goofy "
[1](2c90107fc5be1)      "S-0002c9010b08fb60"[24]                # lid 2 lmc 0 "MT47396 Infiniscale-III Mellanox Technologies" lid 3 4xSDR
