From: Karthikeyan Periyasamy <quic_periyasa@xxxxxxxxxxx> In the Inter Multi-Link Operation, the primary device is expected to receive the partner device buffer. Therefore, each device initializes the partner device buffer in their cmem configuration. So add a helper function to initialize the partner device buffer in their cmem configuration.
