FUNCTION: TXC_ENVOY_IngressPacketCtrlSet
DESCRIPTION: This function sets the control of the ingress packet stream received
from an Ethernet port.
INPUTS: handle: Instance of the Envoy device to configure.
port: The ethernet MAC port to configure. For Envoy-CE2, the range is from
0 to 15, corresponding to ethernet physical port 1 to 8. For Envoy-CE4,
the range is 0 to 31, corresponding to ethernet physical ports 1 to 32.
The value 0xFFFF is used to configure all ethernet ports of specified
terminal the same way.
macIfaceDataPtr: a pointer to type TXC_IfMAC_CONFIG_STRUCT.
RETURNS: TXC_NO_ERR or an appropriate specific error code.
