As nobody reacted to our discussion thread [1] with other arguments, I
stayed on my initial position:
- 2 bytes more in the mbuf structure is always good to have
- no performance impact detected (see my test reports)
- the 48 bits physical address limit will be reached in several years,
and at this time, maybe the cache lines will be 128 bytes? (solving
our initial rte_mbuf issue). So let's just deal with current or near
future hardware.

Thomas's answer on this question [2] was to do that way, so I did not
modify the v1 patches.

Olivier
