From ca920f5b67f1b798a1f86c675ea441b295bf8464 Mon Sep 17 00:00:00 2001 From: Bart Van Assche Date: Fri, 3 Jun 2016 07:58:32 -0700 Subject: IB/mlx4: Fix device managed flow steering support test Perform the test for device managed flow steering support even if memory windows are not supported. I noticed this because smatch reported inconsistent indentation for the device managed flow steering support test.

Data passed to this procedure can come from user-space. Therefore, need to validate port number before proceeding onwards. Note that we check against the number of physical ports declared at the verbs (ib core) level; When bonding is active, the verbs level sees one physical port, even though the low-level driver sees two ports.
