[dpdk-stable] [PATCH 17.11] crypto/qat: fix checks for 3GPP algo bit params

Thu Aug 2 10:18:57 CEST 2018


[ backported from upstream commit 64cb90f882704df2cc18e49437ddfdba088dd898 ]

QAT driver checks byte alignment for KASUMI/SNOW 3G/ZUC algorithms using
cipher/auth_param, which are not initialized at this moment yet. Use
operation params instead.

Fixes: a59ffe7eb952 ("cryptodev: add bit-wise handling for SNOW 3G")
