Not sure what you mean by all 5 lsaps. Ya might say there are six, but
that's not technically correct. The SNA lsaps are 0x04, 0x08 and 0x0C.
These are the lsap values you'd see in the command frames; the response
frames flip the first bit, resulting what most people call the other three
lsaps, 0x05, 0x09 and 0x0D, though they're not 'really' lsaps. Anyway, back
to your question, the first ACL, having all 0s in the mask, would mean all
the bits in the dsap/ssap pair must be matched exactly and therefore would
only match on 0x0D0D, so that's not it. The second one is correct.
