Message-Id: <1230142896-15533-4-git-send-email-ron.mercer@qlogic.com> Date: Wed, 24 Dec 2008 10:21:35 -0800 From: Ron Mercer <ron.mercer@...gic.com> To: netdev@...r.kernel.org Cc: ron.mercer@...gic.com Subject: [PATCH 4/5] qlge: bugfix: Fix rx ring and large and small rx buffer length settings. The length field for rx ring and buffer rings is 16-bits. To indicate a maximum length of 65536 the value should be set to zero.
