When sending commands to Kernel FPA PF driver, it expects the
aura to be in the range of 0 to 16 for a given FPA pool.
In OCTEON TX we map a pool,aura pair as single mempool handle,
always set the aura id to 0 for a given FPA pool.

When building send command for a given descriptor it expects
it to contain the AURA identifier of the pool that it belongs
to rather than the pool identifier itself.
