So to fix the documentation, we should change the word "or" to "and".

BTW, this documentation is actually wrong. You can't enable rp_filter
on all interfaces with
echo 1 > /proc/sys/net/ipv4/conf/all/rp_filter
You must do that in conjunction with
echo 1 > /proc/sys/net/ipv4/conf//rp_filter
for it to work for .
This is really counter-intuitive but it's apparently how it's always
