Re: ib_srpt and mellanox mthca device

Hi Roland!

Also another question. I still cannot create target with targetcli nor 
with configfs. It alays said that wwn is invalid and seems cannot 
register ib device. Can it be related to order of module loading. I have 
this problems both with mlx4 and mthca device. Or may it be related to 
firmware version. Its branded HP devices. Can I use non OEM firmware for 
them?
