[dpdk-dev] [PATCH] app/test: fix array overflow warning with gcc 4.5

[Tomasz Kulasek <tomaszx.kulasek@intel.com>]

DPDK/app/test/test_cryptodev.c: In function ‘create_snow3g_cipher_operation
_oop.clone.15’: DPDK/x86_64-native-linuxapp-gcc/include/rte_memcpy.h:796:14
error: array subscript is above array bounds.

In test_cryptodev.c:
2429	rte_memcpy(sym_op->cipher.iv.data, iv, iv_len);

When iv_len is declared as 'unsigned int', rte_memcpy evaluates code for
buffer size bigger than 255, but while 'iv' array is 64 bytes long, it
causes 'above array bounds' warning in gcc 4.5 and breaks compilation.

Using uint8_t as a size of copied block prevents to evaluate in rte_memcpy
code for length bigger than 255, causing the problem.

The root of this issue and solution is the same as for commit 2c007ea10616
("app/test: fix array overflow warning with gcc 4.5")

Fixes: 9727af14b032 ("app/test: add out-of-place symmetric crypto
       operations")
