The timer configuration is propagated in network protocol, so
misconfigured Linux box
could survive but effect other devices on the network that are less
robust. Maybe the
small values would cause some other bridge to crash, go infinite loop, ...
More likely robust devices might ignore our packets (because values out
of range), leading to
routing loops and other disasters.
The kernel does need to stop administrative settings from taking out a
network. If someone
has a custom device or other non-standard usage, they can always rebuild
the kernel and
remove the range check.
