[Click] encapsulating from IPEncap to EtherEncap exception

[Hristo Asenov]

Hello,

We are currently using CLICK to form our own packets, with the DATA field of IP packet set to our own value, which we get from an arbitrary socket. We are using IPEncap to encapsulate our data in a valid IP packet, then using EtherEncap to encapsulate it into an ethernet frame. Our script looks like:

Socket(TCP, 0.0.0.0, 7777)
   -> Print("From Socket: ")
   -> IPEncap(0, 192.168.0.2, 192.168.0.3)
   -> Print("From IP: ")
   -> IPPrint("From IP: ")
   -> EtherEncap(0x0800, 0:0:0:0:0:0, 1:1:1:1:1:1)
   -> Print("From Ethernet: ")
   -> Queue 
   -> ToDevice(eth0);

Going from IPEncap to EtherEncap, we are getting the exception "expensive Packet::push; have 8 wanted 14". I have a feeling that the exception is inside IPEncap. The packet is still transmitted over the network, however we have no idea why that exception is being generated. If anyone can help us out, it would be appreciated.

                                                                       Hristo
