From 5920869f1ec263fee4255ec71d333c118406a419 Mon Sep 17 00:00:00 2001 From: Jack Morgenstein Date: Mon, 10 Dec 2007 05:25:23 +0200 Subject: [PATCH] mlx4_core: Fix max_eqs masking in QUERY_DEV_CAP log_max_eqs is a 4-bit field, not a 3-bit field in the response to the QUERY_DEV_CAP FW command, so we should mask with 0xf instead of 0x7 when reading it.
