Code is a little over 9,000 bytes, but significant space is taken by the
DHCP, DNS, and ARP subsystems that all use dedicated buffers for send
operations. Incoming buffer should be 1514 bytes, and outgoing buffer is
1500 because the protocol headers are stored separate from the payload (see
ETH.S on disk 2). In future, I will probably have to introduce support for
multiple receive buffers in order to support simultaneous TCP and UDP
sockets.
