From 630c3183cec33b502e80846e728c3ff165d1c84d Mon Sep 17 00:00:00 2001 From: Sagi Grimberg Date: Tue, 13 Oct 2015 19:12:59 +0300 Subject: [PATCH] IB/iser: Enable SG clustering iser is perfectly capable supporting SG clustering as it translates the SG list to a page vector. Enabling SG clustering can dramatically reduce the number of SG elements, which doesn't make much of a difference at this point, but with arbitrary SG list support, reducing the number of SG elements can benefit greatly as as it would reduce the length of the HW descriptors array.
