The patch enhances the tx_checksum command and reworks csum forwarding engine
due to the change of tx_checksum command.
The main changes of the tx_checksum command are listed below,
1. add "tx_checksum set tunnel (hw|sw|none) (port-id)" command
2. add "tx_checksum set outer-ip (hw|sw) (port-id)"
The DEV_TX_OFFLOAD_OUTER_IPV4_CKSUM flag is added in i40e capability set, which
means the i40e supports TX checksum offload of tunneling packet.

In the current codes, the "tx_checksum set (ip|udp|tcp|sctp|vxlan) (hw|sw)

The name of the rte_eth_fdir_flow's rte_eth_ipv6_flow attribute,
'ip6_flow', clashes with a macro defined in
/usr/include/netinet/ip6.h, such that when DPDK is linked with an

Hey Everybody,
Thanks for the feedback. Yeah, we're pretty sure that the amount of memory
we work with is atypical, and we're hitting something that isn't an issue

I don't know if other reviewers ask you to split so many patches. But I
would like merge some of them, because some are doing same affairs(just
using different args), others should be add/remove affairs. Those could
be merge to one patch, although it is much more easier for review.

The patch adds rte_eth_dev_save() and rte_eth_dev_get_changed_port().
rte_eth_dev_save() is used for saving current rte_eth_dev structures.
rte_eth_dev_get_changed_port() receives the rte_eth_dev structures, then
compare these with current values to know which port is actually
attached or detached.
rte_eth_dev_shutdown() is called when PCI device is closed.

To remove assumption, do like followings.
- Add 'attached' member to rte_eth_dev structure.
This member is used for indicating the port is attached, or not.
- Add rte_eth_dev_allocate_new_port().
This function is used for allocating new port.

What you're doing is an unusual use case and this is open source code where

Hey Folks,
Our DPDK application deals with very large in memory data structures, and
can potentially use tens or even hundreds of gigabytes of hugepage memory.
During the course of development, we've noticed that as the number of huge
pages increases, the memory initialization time during EAL init
