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. R.
