This appears to be one of the dual-licensed drivers, that are the result of some BSD driver having been ported to Linux with the original copyright left intact. In the case of lmc, a comment states, that it was originally derived from the "de" driver (DEC Ethernet) by Matt Thomas, although it appears to have been rewritten from scratch (with the BSD copyright notice retained). The same happened to the ncr 53c810 driver which was ported to Linux and then back-ported to FreeBSD as with extensions developed under Linux to better support later generations of the controller chip. > I suspect the former but my attempts to contact the author were unsuccessful > so it is probably better to just drop it. > >> Inc is for very old interconnect to telco... So maybe that's safe to delete. It appears to be a strange beast that uses the Ethernet chip to generate a bit stream which is then converted to HDLC. Not sure whether these were used for Frame Relay or to connect to the British X.25 JANET, a few decades ago. Perhaps also to connect to SS7 signaling networks? Regards, STefan
