Forgot one minor comment. Suggest reword title to be "fix use of internal
struct" and add fixes line below to commit body.

Reword title to be "fix use of ..." and include:

Fixes: a4677f78368b ("examples/ipsec-secgw: add target queues in flow actions")
Cc: nelio.laranjeiro@6wind.com

With that addition patch looks ok to me.

As with the other patches, please treat this as a bug-fix and include a
fixes line for each app fixed. Apps should not be using internal DPDK data
structures directly.

[dpdk-dev] [v2 2/3] examples/ip_fragmentation: fix use of internal struct

[Marcin Zapolski]

Modify ip_fragmentation example app to use rte_eth_info_get instead
of global rte_eth_devices structure.
Apps should not be using internal DPDK data structures directly.
