the srp initator creates a virtual scsi device driver. this virtual
device driver has a .max_sectors paramters associated with it. you can
tune this with the max_sect= during login for the openfabrics stack.
no idea, how this is tuned on ibgold.
take a look at /sys/block/sd<whatever>/queue/{max_hw_sectors_kb,max_sectors_kb}
if you arent using direct i/o, use direct i/o. you could just tune
the page size of the ddn to 256k.
