[dpdk-dev] [PATCH] common/cpt: add support for new firmware

[dpdk-dev] [PATCH] common/cpt: add support for new firmware

[Anoob Joseph]

From: Ankur Dwivedi <adwivedi@marvell.com>

With the latest firmware, there are few changes for zuc and snow3g.

1. The iv_source is present in bitfield 7 of minor opcode. In the
old firmware this was present in bitfield 6.

2. Algorithm type is a 2 bit field in new firmware. In the old
firmware it was named as cipher type and it was a 1 bit field.
