> 1. Summary
> ----------
>
> This case proposes enhancements to the driver administration framework
> introduced by PSARC 2007/429 to get/set default values for properties
> from/to the driver from the user-space libdladm library.
>
> Release binding: minor
>
>
> 2. Description
> --------------
> The default values of some properties may not be known a priori
> to dladm. For example, the default MTU of ethernet links is
> 1500 bytes, whereas that for InfiniBand is 2044, and the value can
> vary for tunnel links. In these cases, dladm will have to send
> a system call to the driver to obtain the default value of the property.
> Also, the "reset-linkprop" command will have to notify the driver
> that the value of the property must be reset to the default value for
> that driver.
>
> This feature is achieved by sending a DLDIOC{SET, GET}PROP ioctl
> to the driver with the pr_flags set to DLD_DEFAULT. The driver
> may then recognize the DLD_DEFAULT flag and return the default value
> for the property (in the case of a GETPROP), or reset the property
> to the default value (for SETPROP).

> Interface Classification Comments
