The simple ipc layer just passes the buffer to the pkt-line layer
and it takes a "const char *", so to avoid confusion I just left
the type is it was. If later we want to fix pkt-line, we can
investigate passing a "const unsigned byte *" value down the
call chain, but that is more than I want to do right now.
