	Sort of off topic, but the iSCSI MaxBurstLength doesn't set the max transfer 
size, it simply is the amount of data that can be sent without a R2T. If the 
transfer is larger then you have to wait for the R2T. In practice it ends up 
controlling the _minimum_ amount of buffer space that needs to be available 
_before_ the transfer starts, otherwise performace sucks.
