But software builds the ethernet packets! It puts the destination MAC
address, followed by the source MAC address, followed by the byte-count,
followed by the DATA where DATA is (or could be) an IP packet or
a NETBIOS or IPX/SPX, etc.,,, packet into the SNIC buffer (Serial Network
Interface Controller). This 'hardware' header is available at both ends of
the link. A broadcast packet is received by everybody because the
hardware destination address is FF:FF:FF:FF:FF:FF, not because there
is ".255" at the end of the IP address that is encapsulated in the
DATA portion of the packet!
We use ethernet controllers as modems on two high-speed, ping/ponged,
data links on one of our CAT Scanners. The resulting NRZ bit-stream does
ultra-wide-band frequency modulation using a "missing-carrier" scheme.
The resulting signal is very noise-immune and is used to send image
data from a rotating scanner to the stationary assembly with no
electrical connections at all. The source MAC address is "BERNIE"
and the destination address is "GORDON", the founder of Analogic
Corporation, and co-inventor of this patented scheme.
It is less-than-trivial to use any MAC address you want with Ethernet.

Dick Johnson
