This line represents the default values.
This line represents the default values.
BYTE 2: Adaptive IFS. This byte indicates the minimum number of PCI clocks counted
between sending two transmit frames on the wire. The resolution of this counter is 8 PCI
clocks making the range from 0 to 2040 PCI clocks.
Default - 0.
Recommended - 0.
BYTE 3.
— Bit 3 - Terminate Write on Cache Line. This bit is reserved on the 82557 and should be set

to 0.
However, when this bit is set on the 82558 or a later generation controller, the device
attempts to terminate its write accesses on cache lines. This may yield lower PCI
throughput in systems which are not extremely cache line oriented. This bit should
therefore be set only in systems that are extremely cache line oriented.
0 = Terminate Write on Cache Line disabled.
