From 1bcdc32cf4d94442eba79599ce8438ea0b8f78b5 Mon Sep 17 00:00:00 2001 From: Michael Chan <mchan@broadcom.com> Date: Thu, 10 Dec 2009 15:40:57 +0000 Subject: [PATCH] cnic: Send delete command when shutting down iSCSI ring. This step is necessary on the bnx2x devices when restarting the iSCSI ring. Without it, the firmware can assert and cause bnx2x to report errors.
