From bfead3b2cb4607c71831423c3ee97d22cd0c9dcb Mon Sep 17 00:00:00 2001 From: Jayamohan Kallickal Date: Fri, 23 Oct 2009 11:52:33 +0530 Subject: [SCSI] be2iscsi: Adding msix and mcc_rings V3 This patch enables msix for be2iscsi. It also enables use of mcc_rings for fw commands. Since the mcc eq creation is dependent on msix I am sending as one patch Signed-off-by: Jayamohan Kallickal Signed-off-by: James Bottomley --- drivers/scsi/be2iscsi/be_mgmt.c | 69 +++++++++++++++++++++++++++++++---------- 1 file changed, 52 insertions(+), 17 deletions(-) (limited to 'drivers/scsi/be2iscsi/be_mgmt.c') diff --git a/drivers/scsi/be2iscsi/be_mgmt.c b/drivers/scsi/be2iscsi/be_mgmt.c index 12e644fc746e..79c2bd525a84 100644 --- a/drivers/scsi/be2iscsi/be_mgmt.c +++ b/drivers/scsi/be2iscsi/be_mgmt.c @@ -35,7 +35,6 @@ unsigned char mgmt_get_fw_config(struct be_ctrl_info *ctrl, be_cmd_hdr_prepare(&req->hdr, CMD_SUBSYSTEM_COMMON, OPCODE_COMMON_QUERY_FIRMWARE_CONFIG, sizeof(*req));
