In order to upload helper module automatically, helper alias name
is needed. so that MODULE_ALIAS_NFCT_HELPER() should be added.
And unlike other nat helper modules, the nf_nat_snmp_basic can be
used independently.
helper name is "snmp_trap" so that alias name will be
"nfct-helper-snmp_trap" by MODULE_ALIAS_NFCT_HELPER(snmp_trap)
test command:
%iptables -t raw -I PREROUTING -p udp -j CT --helper snmp_trap
%lsmod | grep nf_nat_snmp_basic
We can see nf_nat_snmp_basic module is uploaded automatically.
