> When building with gcc 11.2.0, the compiler warns as follows:
> In function 'memcpy',
>     inlined from 'openssl_set_session_auth_parameters' at
> ../drivers/crypto/openssl/rte_openssl_pmd.c:699:3,
>     inlined from 'openssl_set_session_parameters' at
> ../drivers/crypto/openssl/rte_openssl_pmd.c:826:9:
> /usr/include/aarch64-linux-gnu/bits/string_fortified.h:29:10: warning:
> '__builtin_memcpy' forming offset [4, 8] is out of the bounds [0, 4] [-Warray-
> bounds]
> 
> Fixed the warning by copying up to string / buffer size.
