Add several levels of DEBUG prints so that you can limit the noise to
the severety of your problem.
DEBUG_LL_STATE = Link local state machine changes
DEBUG_DEV_PKT = Packets or info directed to the device
DEBUG_NET_PKT = Packets on info on the network at large
DEBUG_INT_STATE = Internal network state changes

Cisco's arp-proxy feature fails to ignore the link-local address range
This means that a link-local device on a network with this Cisco
equipment will reply to ARP requests for our device (in addition to
our reply).
If we happen to reply first, the requester's ARP table will be
populated with our MAC address, and one packet will be sent to us...
shortly following this, the requester will get an ARP reply from the
Cisco equipment telling the requester to send packets their way
instead of to our device from now on.
This work-around detects this link-local condition and will delay
replying to the ARP request for 5ms so that the first packet is sent
to the Cisco equipment and all following packets are sent to our
device.

Link-local support will need to send ARP packets, but needs more
fine-grained control over the contents. Split the implementation
into 2 parts so link-local can share the code.

Use the NetArpTxPacket for the ARP packet, not to hold what used to
be in NetTxPacket.
This saves a copy and makes the code easier to understand.
