I meant removing brnf_sysctl_call_tables function, not the sysctls
themselves, all it does is change values != 0 to 1. Or did you
actually mean that something in userspace might depend on reading
back the value 1 after writing a value != 0?

I was going farther, because don't really see the value of having
a sysctl for this. It seems better to just not load filters if
they aren't going to be used. Having another enable/disable hook
just adds needless complexity.

These sysctls control whether bridged packets will be handled
by iptables and friends. The bridge netfilter code always
handles bridged packets, and iptables might be loaded for
different reasons. So I don't see how that would work.

I think it should be specified in the ebtables ruleset, but
the current netfilter infrastructure doesn't allow to do that
