FC and FCoE Driver Parameters
Note: The FC and FCoE driver parameters determine some aspects of the driver’s
behavior. There are two main types, static and dynamic. Changes to the static
parameters require a driver reload for the change to take effect. Changes to
most dynamic parameters take effect immediately; some do not take effect until
there is a link-down/link-up sequence.
See the following section and “Dynamic FC and FCoE Driver Parameters” on page 826,
respectively.
Static FC and FCoE Driver Parameters
Changes to static parameters require a driver reload for the change to take effect.
Table 3-1 lists the static FC and FCoE driver parameters.
