Transmit TX descriptor 2
If this bit is enabled, MAC will begin to transmit data that are stored in TX
buffer. In former, driver had already written data that is assigned to TX
descriptor2 to TX buffer. This bit will be cleared by hardware when MAC
finished the transmission.

RX Buffer Monitor Enable
When this bit is enabled, MAC will monitor the status of receive buffer.
1 = enable
0 = disable
Reserved.
RX Packet TCP/IP Checksum
When this bit is set, AX88180 will check the checksum of the received
packet that is IP, TCP or UDP packet. If there is checksum error, AX88180
will drop the packet and RXCHKSUMCNT counter will add 1.
1 = enable
0 = disable
Reserved
RX Buffer Protection
When this bit is enabled, MAC will protect the RX buffer to avoid overrun.
For normal operation, this bit should be enabled in initial stage.
1= enable
0= disable
