Memory Read Multiple
When set, the DM9102D will use memory read multiple command (C/BE3~0 1100)
when it initialize the memory read burst transaction as a master device
When reset, it will use memory read command (C/BE3 ~ 0 = 0110) for the same
master operation
Reserved
Software Reset
When set, the DM9102D will make a internal reset cycle. All consequent action to
DM9102D2 should wait at least 32 PCI clock cycles for its self-cleared.

Description
Transmit Descriptor Polling Command
Writing any value to this port will force DM9102D to poll the transmit descriptor. If
the acting descriptor is not available, transmit process will return to suspend state.
If the descriptor shows buffer available, transmit process will begin the data
transfer.
