CAUTION: When setting RxIntDelay to a value other than 0, adapters based
on the Intel 82543 and 82544 LAN controllers may hang (stop
transmitting) under certain network conditions. If this occurs a
message is logged in the system event log. In addition, the
controller is automatically reset, restoring the network
connection. To eliminate the potential for the hang ensure that
RxIntDelay is set to 0.
