[ovs-dev] OVS OpenFlow -- Transferring "metadata" between bridges

Hello all,

I am doing a classification of a packet in one bridge OF pipeline and
writing the result to
"metadata" field (or Nicira's registers 0..7).

When the packet is sent across bridges (for example via a patch port) this
data is lost, the only field that i found to still exists across bridges is
the packet mark field.

Is there any other mechanism/field i can use to transfer classification
data across bridges?
(They are both in the local machine)
