As far as I remember the only historic use of LLC2 was netbeui (which I've probably misspelled). That was really replaced by NetBios of TCP. So we are in the age of 8-bit ISA ethernet cards that stood no chance of receiving the 15 back-to-back ethernet frames they issued credit for. Oh, and another stunningly bad ISA card that sometimes failed to indicate there was a frame in its rx fifo (for pio reads) until the following frame arrived (even the fifo byte count was wrong). I can't remember exactly why that completely broke llc2.
