[NETFRAME] IPv4 checksum not being computed

[Carlos Vicente]

Thanks much. 

I will give Net::Frame a try later.

Is there a way to avoid this warning?:

    Net::Packet::Dump::_startTcpdump: lookupnet: eth1.60: no IPv4
address assigned

I have tried 'no warnings' and passing -X to perl, but no luck.

Thanks for your help.
