Hi Pablo,

I successfully appied the patch against 3.4.10 but it is failing to compile, 
likely because of a lack of definition for the ecache struct.

the specific error from gcc is:

net/netfilter/nf_conntrack_core.c:258:9: error: dereferencing pointer to 
incomplete type

(plus all the other relevant lines using the ecache ptr)

Kind Regards,
Oliver
