From 1457edc72d187f452be1374c7d9281f1dfa16f32 Mon Sep 17 00:00:00 2001 From: Joachim Fenkes Date: Mon, 10 Dec 2007 12:20:57 +0100 Subject: IB/ehca: Return correct number of SGEs for SRQ Firmware would round up the number of SGEs to four, because the WQE structure holds four SGEs. For SRQ, only three are supported, so return a fixed value instead.
