Out of order(OOO) processing requires initiator, switch
and target to support OOO. In today¹s environment, none
of the switches support OOO. OOO requires extra buffer
space which affect performance. By turning ON this feature
in QLogic's FW, it delays error recovery because droped
frame is treated as out of order frame. We¹re turning OFF
this option of speed up error recovery,
