- Usage:
	- cat /proc/mtketh/dbg_regs
- What's new:
	- FE_INT_STA: Frame Engine Interrupt Status
	- PSE_IQ_STA5: PSE Input Queue Status part5
	- PSE_OQ_STA5: PSE Output Queue Status part5
	- PDMA_CRX_IDX: PDMA CPU pointer
	- PDMA_DRX_IDX: PDMA DMA pointer
	- QDMA_CTX_IDX: QDMA CPU pointer
	- QDMA_DTX_IDX: QDMA DMA pointer
	- MAC_P1_FSM: GMAC1 finite state machine
	- MAC_P2_FSM: GMAC2 finite state machine
	- FE_CDM3_FSM: CDM finite state machine for WDMA0
	- FE_CDM4_FSM: CDM finite state machine for WDMA1
	- SGMII_EFUSE: SGMII E-Fuse value, which can be used
		       to check whether DUT is calibrated
	- SGMII_RX_CNT: SGMII false carrier count, which can
			be used to check whether SGMII detects
			frame starts
	- WED_RTQM_GLO: WED Rx route QM global configuration,
			which can be used to check whether
			WED stays in Q_FULL state
