Wrong P2P device link id value of 0 was introduced in ath12k_mac_op_tx() by [1]. During the P2P negotiation process, there is only one scan vdev with link ID 15. Currently, the device link ID is incorrectly set to 0 in ath12k_mac_op_tx() during the P2P negotiation process, which leads to TX failures. Set the correct P2P device link ID to 15 to fix the TX failure issue.
