Message-Id: <1230671545-19084-4-git-send-email-ron.mercer@qlogic.com> Date: Tue, 30 Dec 2008 13:12:24 -0800 From: Ron Mercer <ron.mercer@...gic.com> To: davem@...emloft.net, jeff@...zik.org Cc: netdev@...r.kernel.org, linux-driver@...gic.com, ron.mercer@...gic.com, bhutchings@...arflare.com, hch@...radead.org Subject: [PATCH 4/5] qlge: bugfix: Fix ring length setting for rx ring, large/small The length field for these rings is 16-bits. If the length is the max supported 65536 then the setting should be zero.
