Routine Description:
This routine is provided by the Kernel Forwarder to filter packets being sent out
by NB/SPX/TDI thru' IPX - does not include those sent out by the Forwarder (external sends)
Arguments:
LocalTarget - the NicId and next hop router MAC address
FwdAdapterContext - Forwarder's context - preferred NIC if not INVALID_CONTEXT_VALUE
Packet - packet to be sent out
IpxHeader - points to the IPX header
Data - points to after the IPX header - needed in spoofing of keepalives.
PacketLength - length of the packet
fIterate - a flag to indicate if this is a packet for the iteration of which the
Fwd takes responsibility - typically type 20 NetBIOS frames
Return Value:
STATUS_SUCCESS - if the preferred NIC was OK and packet passed filtering
STATUS_NETWORK_UNREACHABLE - if the preferred was not OK or packet failed filtering
STATUS_PENDING - if preferred NIC was OK but line down
Forwarder should give us a different status than STATUS_NETWORK_UNREACHABLE for changed NIC
