Hi Mani, ath11k patch was sent as part of the same series to everybody included in this patch as well under the name of "[PATCH 2/2] wifi: ath11k: use unique QRTR instance ID". If you did not receive it due to some kind of error, its available at the linux-wireless patchwork[1] or ath11k mailing list[2].
