sq_size
"Configure SQ size", used to choose send queue size for offloaded connections
and SQ size determines the maximum SCSI commands that can be queued. SQ
size also has a bearing on the number of connections that can be offloaded; as
QP size increases, the number of connections supported will decrease. With the
default values, the adapter can offload 28 connections.
Defaults: 128
Range: 32 to 128
Note that QLogic validation is limited to a power of 2; for example, 32, 64, 128.
rq_size
“Configure RQ size”, used to choose the size of asynchronous buffer queue size
per offloaded connections. RQ size is not required greater than 16 as it is used to
place iSCSI ASYNC/NOP/REJECT messages and SCSI sense data.
Defaults: 16
Range: 16 to 32
Note that QLogic validation is limited to a power of 2; for example, 16, 32.
event_coal_div
"Event Coalescing Divide Factor", performance tuning parameter used to
moderate the rate of interrupt generation by the iSCSI firmware.
Defaults: 2
Valid values: 1, 2, 4, 8
last_active_tcp_port
“Last active TCP port used”, status parameter used to indicate the last TCP port
number used in the iSCSI offload connection.
Defaults: N/A
Valid values: N/A
Note: This is a read-only parameter.
ooo_enable
“Enable TCP out-of-order feature”, enables/disables TCP out-of-order rx handling
feature on offloaded iSCSI connections.
Defaults: TCP out-of-order feature is ENABLED. For example:
insmod bnx2i.ko ooo_enable=1
or
modprobe bnx2i ooo_enable=1
