That's exactly the problem, the 3 possible LANCE's for DECstations are
onboard in [23]100 codenamed pmax LANCE, onboard in 5000's codenamed
IOASIC LANCE and TURBOchannel option cards codenamed PMAD LANCE and
all 3 use different memory access mechanisms, read the comments in
drivers/net/declance.c. :-)
