The LLC SAP for NetBIOS is F0. DSAP, SSAP would be FOFO.
SNA uses a bunch of SAPs. I have seen 0x04, 0x05, 0x08, 0x0C. I haven't
seen D0. In fact, D0 would be a global DSAP because the first bit is set.
In the SSAP the first bit is the command/response bit. The bit being set
means that the frame is a response.
What are the masks you mentioned? What are you working on??
