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.

1b = Enable internal reset on force TCO command.
0b = Force TCO command has no impact on the 82574.
1b = Disables SMBus ARP functionality.
0b = Not supported.
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.
