A method performed by a transmitting device is disclosed herein. The transmitting device operates in a communications network. The transmitting device performs a reset on a buffer of the transmitting device. The transmitting device then switches, based on the performed reset, a first value in an indication to a second value. The indication is of the reset of the buffer. The transmitting device sets the indication to the second value for all packets generated by the transmitting device after the performed reset. This is set until the second value is switched again by the transmitting device in another indication, based on another performed reset of the buffer. The transmitting device then sends the indication with the second value to a receiving device operating in the communications network. The second value indicates that the reset was performed by the transmitting device.
