The NXP NETC switch tag is a proprietary header added to frames after the
source MAC address. The switch tag has 3 types, and each type has 1 ~ 4
subtypes, the details are as follows.
Forward NXP switch tag (Type=0): Represents forwarded frames.
- SubType = 0 - Normal frame processing.
To_Port NXP switch tag (Type=1): Represents frames that are to be sent
to a specific switch port.
- SubType = 0. No request to perform timestamping.
- SubType = 1. Request to perform one-step timestamping.
- SubType = 2. Request to perform two-step timestamping.
- SubType = 3. Request to perform both one-step timestamping and
two-step timestamping.
To_Host NXP switch tag (Type=2): Represents frames redirected or copied
to the switch management port.
- SubType = 0. Received frames redirected or copied to the switch
management port.
- SubType = 1. Received frames redirected or copied to the switch
management port with captured timestamp at the switch port where
the frame was received.
- SubType = 2. Transmit timestamp response (two-step timestamping).
In addition, the length of different type switch tag is different, the
minimum length is 6 bytes, the maximum length is 14 bytes. Currently,
Forward tag, SubType 0 of To_Port tag and Subtype 0 of To_Host tag are
supported. More tags will be supported in the future.
