  3. linux-gen: buffer: remove data size member from odp_buffer_hdr_t 

    Data size is constant for all buffers from the same pool, so there is no
need to store the value in the buffer header.

  5. linux-gen: pool: add inlined accessors for selected pool parameters 

    Add inlined accessors for pool_t members pool_hdl and uarea_size. This
enables removing the matching members from odp_buffer_hdr_t, and thus
reduces per buffer overhead.

  6. linux-gen: pktio: add pktio capability to pktio_entry_t

it inside pktio_entry_t.
