Subject: [PATCH V5 2/5] ipath,qib: Expose max_sge_rd correctly
Date: Sun, 05 Jul 2015 12:44:47 -0500 [thread overview]
Message-ID: <20150705174446.10042.77074.stgit@build2.ogc.int> (raw)
In-Reply-To: <20150705174353.10042.39648.stgit@build2.ogc.int>
Applications must not assume that max_sge and max_sge_rd are the same,
Hence expose max_sge_rd correctly as well.
