0 = Link is not established
The link status bit is implemented with a latching function, so that the
occurrence of a link failure condition causes the link status bit to be
cleared and remain cleared until it is read via the management
interface
Jabber Detect
1 = Jabber condition detected
0 = No jabber
This bit is implemented with a latching function. Jabber conditions
will set this bit unless it is cleared by a read to this register through a
management interface or a PHY reset. This bit works only in 10Mbps
mode

11.3 PHY ID Identifier Register #1 (PHYID1) - 02
The PHY Identifier Registers #1 and #2 work together in a single identifier of the DM9601. The Identifier consists
of a concatenation of the Organizationally Unique Identifier (OUI), a vendor's model number, and a model
revision number. DAVICOM Semiconductor's IEEE assigned OUI is 00606E.

OUI Most Significant Bits
This register stores that bit 3 to 18 of the OUI (00606E) are
mapped to bit 15 to 0 of this register respectively. The most
significant two bits of the OUI are ignored (the IEEE standard refers
to these as bit 1 and 2)
