The RTL8309SB will accept management frames with
preamble suppressed.
The RTL8309SB accepts management frames without
preamble. 32 minimum preamble bits are required for the
first SMI read/write transaction after reset. One idle bit is
required between any two management transactions as
defined in the IEEE 802.3u specifications.

1: Link is established. If the link fails, this bit will be 0 until
after reading this bit again
0: Link has failed
1: Jabber detect enabled
0: Jabber detect disabled
The jabber function is disabled in 100Base-TX operation.
Jabber occurs when a predefined excessively long packet is
detected for 10Base-T. When the duration of TXEN exceeds
the jabber timer (21ms), the transmission and loopback
function are disabled and the COL LED starts blinking. After
TXEN goes low for more than 500 ms, the transmitter will be
re-enabled and the COL LED will stop blinking. Jabber
detect is supported only in 10Base-T operation.
