Hi,

the change introduced by itojun in rev. 1.13 of if_spppsubr.c simply
adds explicit parentheses that agree with C's operator precedence.
Thus, it does _not_ fix the problem the PR is about.

Instead, removing the #if 0's from sppp_ipcp_tlf() and sppp_ipcpv6_tlf()
fixed the problem for me. However, I do not know who put those #if 0's
there and I don't understand why. Unfortunately, I am very short
of time and therefore unable to test a current revision. I will do
so as soon as I get to it.

Regards,

cu Jo
