Not only GMAC, the wireless chain algos such as SNOW3G requires IV in auth field (test_snow3g_cipher_auth() in unit test).
Rte_crypto_sym_op has auth_iv.offset to indicate where the iv is stored in crypto op, so the virtual and physical addresses of it can be deducted through the offset, but not yet for rte_crypto_sym_vec.
