Transmit Priority Level 6
Transmit Priority Level 7 (Highest)
Bits [5:4]
Reserved
Bits [7:6]
00 - No Filtering
01 - Exclusive Filtering (x<=RLOW or x>=RHIGH)
10 - Inclusive Filtering (RLOW<x<RHIGH)
11 - Invalid
Bits [4:0]:
Vendor specified link status register address (null value means don’t use it)
(Default 00). This is used if the Linkup bit position in the PHY is non-standard
Bits [5]
Disable jabber detection. This is for HomePNA applications or any serial
operation slower than 10 Mbps.
0 = Enable
1 = Disable
Bits [6]
Reserved
Bit [7]:
Half duplex flow control feature
0 = Half duplex flow control always enable
1 = Half duplex flow control by negotiation
