From 60f012396b40a40ea64a27d142e28916099301d1 Mon Sep 17 00:00:00 2001 From: Quinn Tran Date: Fri, 23 Dec 2016 18:06:14 -0800 Subject: [PATCH] qla2xxx: Disable out-of-order processing by default in firmware Out of order(OOO) processing requires initiator, switch and target to support OOO. In today's 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 dropped frame is treated as out of order frame. We're turning OFF this option of speed up error recovery.
