Enable iSCSI optimization feature

This feature, enabled by default, is activated when EqualLogic arrays are detected. It automatically
performs the following:
 Configures jumbo frames to 9216 on all ports.
 Disables unicast storm.
 Enables spanning tree portfast on ports connected to EqualLogic arrays.
 Configures flow control on all ports.
Note: Spanning tree portfast must be manually configured for host facing ports. Refer to Section 2.8.
console#configure
console(config)#iscsi enable
Enabling iSCSI Optimization will enable Flow Control which may cause all the
interfaces to temporarily go down.

Note: If iSCSI optimization is enabled, flow control is automatically configured on all switch ports upon
detection of an EqualLogic Array. If you plan to enable DCB (using Section 3), you may skip this section.
