From 121964ec38d3e17b5ea6183b3c0571df2f4b0eb6 Mon Sep 17 00:00:00 2001 From: Roland Dreier Date: Tue, 9 Oct 2007 19:59:16 -0700 Subject: [PATCH] mlx4_core: Fix meaning of dev->caps.reserved_mtts Everything that uses caps.reserved_mtts expects it to be a count of MTT segments, not MTT entries. So convert the value that the FW gives us to a count of segments.
