Setting Values for Optional Properties

bnx2i Driver

Optional parameters en_tcp_dack, error_mask1, and error_mask2 can be
supplied as command line arguments to the insmod or modprobe command for
bnx2i.

error_mask1 and error_mask2

"Config FW iSCSI Error Mask #", use to configure certain iSCSI protocol violation
to be treated either as a warning or a fatal error. All fatal iSCSI protocol violations
will result in session recovery (ERL 0). These are bit masks.
Defaults: All violations will be treated as errors.
CAUTION
Do not use error_mask if you are not sure about the consequences. These
values are to be discussed with QLogic development team on a
case-by-case basis. This is just a mechanism to work around iSCSI
implementation issues on the target side. Without proper knowledge of
iSCSI protocol details, users are advised not to experiment with these
parameters.

en_tcp_dack

"Enable TCP Delayed ACK", enables/disables TCP delayed ACK feature on
offloaded iSCSI connections.
Defaults: TCP delayed ACK is ENABLED. For example:
insmod bnx2i.ko en_tcp_dack=0
or
modprobe bnx2i en_tcp_dack=0

time_stamps

"Enable TCP TimeStamps", enables/disables TCP time stamp feature on
offloaded iSCSI connections.
Defaults: TCP time stamp option is DISABLED. For example:
insmod bnx2i.ko time_stamps=1
or
modprobe bnx2i time_stamps=1
