5Description:
6		On read, this file returns a string indicating the type of
7		tagging protocol used by the DSA network devices that are
8		attached to this master interface.
9		On write, this file changes the tagging protocol of the
10		attached DSA switches, if this operation is supported by the
11		driver. Changing the tagging protocol must be done with the DSA
12		interfaces and the master interface all administratively down.
13		See the "name" field of each registered struct dsa_device_ops
14		for a list of valid values.
