The kernel still sends 32 bit from what I can see, but this is problem
independent of what the kernel sends. The library handles receiving both
32 and 64 bit counters from the kernel, and stores them in a 64 bit
field in a structure. The getter/setter then access that field, but that
doesn't work if they access only 32 bits of it, at least for big endian.
An alternative fix is to change the nf_conntrack field to 32 bit,
but I would only do that if you never intend for the kernel to send
64 bit counters.
