The variable lives in rtlplayground.c, so it is declared in rtl837x_common.h with the others there, and it follows the naming of the rest. The header carried comments on the externs that the definitions in rtl837x_stp.c repeat, sometimes differently, which is one place too many to keep in step. What only the header had, the value ranges and what the designated arrays hold, moved to the definitions; the rest is gone. Function declarations lost their comments too. The status printer only prints, so its running commentary went. A define replaces the bare 33 in stp_in(), and the note on the loop check is down to what applies at that line.
