[dpdk-dev] [PATCH v2 1/2] net/ixgbe: fix lack of ip type for crypto session

[Mariusz Drost <mariuszx.drost@intel.com>]

When ixgbe_crypto_add_sa() is called, it checks whether the ip type is
IPv6 or IPv4 to write correct addresses to the registers. Type itself
is never specified, and act as IPv4, which is the default value.
It causes lack of support for IPv6.

To fix that, ip type needs to be stored in device private data, based on
crypto session ip type field, before the checking is done.

Fixes: ec17993a145a ("examples/ipsec-secgw: support security offload")
Fixes: 9a0752f498d2 ("net/ixgbe: enable inline IPsec")
