Following patch adds support for NPIV (N-Port ID Virtualization) to the qla2xxx. - supported within switched-fabric topologies only. - supports up to 63 virtual ports on each physical port. The patch has been inlined and attached in a plain text format as well to provide alternative way for using it in the case where the inlined not working. Also, the same patch can be downloaded from following link, ftp://ftp.qlogic.com/outgoing/linux/patches/8.x/8.02.00-k1/0001-qla2xxx- Add-support-for-NPIV-N-Port-ID-Virtualizat.patch Signed-off-by: Seokmann Ju <seokmann.ju@xxxxxxxxxx> --- drivers/scsi/qla2xxx/Makefile | 2 +- drivers/scsi/qla2xxx/qla_attr.c | 164 +++++++++++++ drivers/scsi/qla2xxx/qla_dbg.h | 10 +- drivers/scsi/qla2xxx/qla_def.h | 83 +++++++ drivers/scsi/qla2xxx/qla_fw.h | 91 ++++++- drivers/scsi/qla2xxx/qla_gbl.h | 39 +++- drivers/scsi/qla2xxx/qla_gs.c | 3 + drivers/scsi/qla2xxx/qla_init.c | 168 ++++++++++++-- drivers/scsi/qla2xxx/qla_iocb.c | 28 ++- drivers/scsi/qla2xxx/qla_isr.c | 39 +++- drivers/scsi/qla2xxx/qla_mbx.c | 396 ++++++++++++++++++++++++++++++- drivers/scsi/qla2xxx/qla_mid.c | 497 +++++++++++++++++++++++++++++++++++++++ drivers/scsi/qla2xxx/qla_os.c | 229 +++++++++++-------- 13 files changed, 1594 insertions(+), 155 deletions(-) create mode 100644 drivers/scsi/qla2xxx/qla_mid.c diff --git a/drivers/scsi/qla2xxx/Makefile b/drivers/scsi/qla2xxx/Makefile index 411663a..71ddb5d 100644 --- a/drivers/scsi/qla2xxx/Makefile +++ b/drivers/scsi/qla2xxx/Makefile @@ -1,4 +1,4 @@ qla2xxx-y := qla_os.o qla_init.o qla_mbx.o qla_iocb.o qla_isr.o qla_gs.o \ - qla_dbg.o qla_sup.o qla_attr.o + qla_dbg.o qla_sup.o qla_attr.o qla_mid.o obj-$(CONFIG_SCSI_QLA_FC) += qla2xxx.o diff --git a/drivers/scsi/qla2xxx/qla_attr.c b/drivers/scsi/qla2xxx/qla_attr.c index 8081b63..95bee23 100644 --- a/drivers/scsi/qla2xxx/qla_attr.c +++ b/drivers/scsi/qla2xxx/qla_attr.c @@ -6,8 +6,11 @@ */ #include "qla_def.h" +#include <linux/kthread.h> #include <linux/vmalloc.h> +int qla24xx_vport_disable(struct fc_vport *, bool);
