Chad,

I think we are picking at extremely worthless nits here.

As per 802.3 section 3.2, the bit is NOT defined for a source
address, only for a destination field. It is reserved and must be set
to zero in the source.

I guess it's time to quote from 802.3 Section 3.2.3(3):
"The first bit (LSB) shall be used in the Destination Address field as
an address type designation bit to identify the Destination Address
either as an individual or as a group address. In the Source Address
field, the first bin is reserved and set to 0."

The final sentence I quoted clearly states that a source address with
the LSB of 1 is illegal.
