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