Do not use always_inline. With current compilers using always inline
makes the optimizer generate worse code. The only exceptions would
be where inline is required to make assembly work or you have good benchmark
data that proves that always_inline generates > 1% performance gain.

To much of DPDK use __rte_always_inline as "cargo cult" it is faster setting.
