While testing this patch I noticed that some meta-data is lost when
segmenting packets. With the attached patch it works fine. Some of
the fields may not appear necessary, so here's my reasoning:

- nfct/nfctinfo/nfct_reasm: the xfrm output path does an immediate
  nf_reset, so they were not necessary until now. Queueing can happen
  on any hook, so we need to preserve them.

- nf_bridge: needed for GSO on a bridge device until the deferred
  hooks are removed

- tc_verd/tc_index/input_dev: when directing a packet from a device
  supporting GSO to a device not supporting GSO using tc actions,
  these fields may be set.

Herbert, does this look sane to you?
