[dpdk-dev] [PATCH] crypto: fix incorrect key setting

[Pablo de Lara <pablo.de.lara.guarch@intel.com>]

When ciphering and authenticating in the same operation
(cipher-then-auth or auth-then-cipher),
the cipher key and authentication key was set with the same
key, in SNOW3G, KASUMI and ZUC PMDs.
They were using the key of the first transform structure,
instead of using the keys of the two different transform
structures.

This is not a big issue, since usually, the same key is
used for ciphering and authentication, but keys may be different.

Fixes: 3aafc423cf4d ("snow3g: add driver for SNOW 3G library")
Fixes: 2773c86d061a ("crypto/kasumi: add driver for KASUMI library")
Fixes: cf7685d68f00 ("crypto/zuc: add driver for ZUC library")
