* Signature: dcu_chain_state is 0x6 and dcu_complete_state is 0x1.
*
* The state of each DCU chain (mapped to TX queues) is available from these
* DMA debug registers:
*
* Chain 0 state : Bits 4:0 of AR_DMADBG_4
* Chain 1 state : Bits 9:5 of AR_DMADBG_4
* Chain 2 state : Bits 14:10 of AR_DMADBG_4
* Chain 3 state : Bits 19:15 of AR_DMADBG_4
* Chain 4 state : Bits 24:20 of AR_DMADBG_4
* Chain 5 state : Bits 29:25 of AR_DMADBG_4
* Chain 6 state : Bits 4:0 of AR_DMADBG_5
* Chain 7 state : Bits 9:5 of AR_DMADBG_5
* Chain 8 state : Bits 14:10 of AR_DMADBG_5
* Chain 9 state : Bits 19:15 of AR_DMADBG_5
*
* The DCU chain state "0x6" means "WAIT_FRDONE" - wait for TX frame to be done.
