> Subject: [PATCH] crypto/ipsec_mb: fix zuc256 maximum tag length
>
> The AESNI_MB PMD supports 8 and 16 byte tag lengths for ZUC256 when
> intel-ipsec-mb version is 1.3 or newer.
> The conditional check to enable these tag lengths had the incorrect operator,
> which enabled 8 and 16 byte tag lengths for versions below 1.2, which is not
> supported.
>
> Fixes: 7babda4316f9 ("crypto/ipsec_mb: support all tag sizes for ZUC-EIA3-
> 256")
