Defines the largest SMBus fragment that can be generated by the 82574.
The 82574 does not generate an SMBus fragment containing more than
(SMBus_Fragment_Size + 1) bytes. The value of this field must be Dword
aligned. Bits 9:8 must be set to 00b.
SMBus Notification Timeout.
Each unit adds 1.1 to 1.3 ms. Resolution depends on internal clock, which
might vary its frequency in different power saving modes.
Reserved, set to 0x0.
Reserved
1b = Enable internal reset on force TCO command.
0b = Force TCO command has no impact on the 82574.
1b = The 82574 does not support SMBus ARP functionality.
0b = The 82574 supports SMBus ARP functionality.
This bit defines the Block Read SMBus command that should be used:
0b = SMBus Block Read command is 0xC0.
1b = SMBus Block Read command is 0xD0.
00b = SMBus alert.
01b = Asynchronous notify.
10b = Direct receive.
11b = Reserved.
Reserved, set to 0b.
Size of the manageability code in Dwords.
Reserved, set to 0b.
00b = Tx 2 Kb, Rx 6 Kb, Rest 4 Kb.
01b = Tx 2 Kb, Rx 7 Kb, Rest 3 Kb.
10b = Tx 2 Kb, Rx 8 Kb, Rest 2 Kb.
11b = Tx 2 Kb, Rx 9 Kb, Rest 1 Kb.
