Code Issues Proposed changes

Set bridge-nf-call-* values to 1

Browse Source 
Although the kernel default is 1, some distros override the defaults
via sysctl.conf. Loading br_netfilter manually will show values of
1, but then doing a 'sysctl network restart' will set the values to
0--so go ahead and override these values.

Sets the bridge-nf-call-* values to 1, overriding any distro defaults that
may not be applied due to br_netfilter not being loaded. These values must
be 1 for security groups to work.
