562306a36Sopenharmony_ciDescription:
662306a36Sopenharmony_ci		On read, this file returns a string indicating the type of
762306a36Sopenharmony_ci		tagging protocol used by the DSA network devices that are
862306a36Sopenharmony_ci		attached to this master interface.
962306a36Sopenharmony_ci		On write, this file changes the tagging protocol of the
1062306a36Sopenharmony_ci		attached DSA switches, if this operation is supported by the
1162306a36Sopenharmony_ci		driver. Changing the tagging protocol must be done with the DSA
1262306a36Sopenharmony_ci		interfaces and the master interface all administratively down.
1362306a36Sopenharmony_ci		See the "name" field of each registered struct dsa_device_ops
1462306a36Sopenharmony_ci		for a list of valid values.
