Re: How to send an IP packet from the kernel

I have a dstaddr, srcaddr and the actual data(payload). I need to load IP packet with data(payload) and send the packet out to the net through eth0 .
How do I do this from the kernel?



Why not do it from userspace, with lots of available tools ( http://www.stearns.org/doc/pcap-apps.html , http://www.stearns.org/netreply )?


For reasons that the driver will do extra stuff on this data and this data not always will be/must be available to a user space app.
Some data will be available only inside of the driver. No other processing out of the driver for that data is allowed.
