I am trying to write a module that takes Ethernet packets from the user domain, and injects it into the proper place ( which I think is the sk_buffers ), so that to the IP, TCP layer, the packets look as if coming from the Ethernet device. Can someone please suggest me which files to look into, and which structs to handle, for getting this done. Also, I want to do the reverse task, i.e. take some particular packets ( say which come from a specific port ) from sk_buffers and send it to user space. Please assume that this silly looking Rx/Tx has some importance :) Regards. Vasu.
