15. A method for using redundant frames for time-sensitive networking (TSN), the method comprising:
identifying, by processing circuitry of a device, an Ethernet frame comprising a redundancy tag and an Internet Protocol (IP) packet, the redundancy tag associated with the TSN;
generating, by the processing circuitry, based on the Ethernet frame, a first Wi-Fi frame comprising the redundancy tag and a sub-network access protocol (SNAP) header after an 802.11 medium access control (MAC) header and prior to the redundancy tag, the first Wi-Fi frame further comprising a first encapsulation of the IP packet;
generating, by the processing circuitry, based on the Ethernet frame, a second Wi-Fi frame comprising the redundancy tag and the SNAP header after the 802.11 MAC header and prior to the redundancy tag, the second Wi-Fi frame further comprising a second encapsulation of the IP packet;
transmitting, by the processing circuitry, the first Wi-Fi frame using a first Wi-Fi communication link; and
transmitting, by the processing circuitry, the second Wi-Fi frame using a second Wi-Fi communication link.
