From 4d73f95f708ce540a85113b00f5363d0593d871d Mon Sep 17 00:00:00 2001 From: Bart Van Assche Date: Sat, 26 Oct 2013 14:40:37 +0200 Subject: IB/srp: Make queue size configurable Certain storage configurations, e.g. a sufficiently large array of hard disks in a RAID configuration, need a queue depth above 64 to achieve optimal performance. Hence make the queue depth configurable.
