Due to the use of typeof(*p) by __rcu_dereference_check(),
which was introduced by the Linux changeset
ca5ecddfa8fcbd948c95530e7e817cee9fb43a3d
(rcu: define __rcu address space modifier for sparse) the definition
of the type of a the parameter to rcu_dereference() is needed.
In terms of the datapath, this means that the definition of
struct tbl needs to be available wherever rcu_dereference(dp->table)
is called.

Currently the flow hash table assumes that it is storing flows.
However, we will need additional types of hash tables in the
future so remove assumptions about flows and convert the datapath
to use the new table.
