lnc(4) on PC98 and i386. The ISA front-end supports the same non-PNP network cards as lnc(4) did and additionally a couple of PNP ones. Like lnc(4), the C-bus front-end of le(4) only supports C-NET(98)S and is untested due to lack of such hardware, but given that's it's based on the respective lnc(4) and not too different from the ISA front-end it should be highly likely to work. - Remove the descriptions of le(4), which where converted from lnc(4), from sys/i386/conf/NOTES and sys/pc98/conf/NOTES as there's a common one in sys/conf/NOTES.
