Help text

Compatible driver to support old /sys/bus/dsa/drivers/dsa behavior. The old behavior performed driver bind/unbind for device and wq devices all under the dsa driver. The compat driver will emulate the legacy behavior in order to allow existing support apps (i.e. accel-config) to continue function. It is expected that accel-config v3.2 and earlier will need the compat mode. A distro with later accel-config version can disable this compat config.

Say Y if you have old applications that require such behavior.

If unsure, say N.
