What the implementors of AX.25 on Linux have done is to hand an KISS

the data is prepended.

OK, so perhaps a new DLT_AX25_KISS should be added, to make it clear that this isn't just pure AX.25. (Among other things, some other implementations might happen to provide pure AX.25 headers at some point.)

Is KISS a standard independent of Linux?
