The patches mainly finish following functions:
1) Store and restore all kinds of filters.
2) Parse all kinds of filters.
3) Add flow validate function.
4) Add flow create function.
5) Add flow destroy function.
6) Add flow flush function.

I know you don't change this code. It's moved here. But this implementation is complex and not friendly. Would you like to change it to,
while ((p_5tuple = TAILQ_FIRST(&filter_info->fivetuple_list))) {
TAILQ_REMOVE(&filter_info->fivetuple_list,
p_5tuple, entries);
rte_free(p_5tuple);
}
The same below.

To my opinion, that the filter is 5-tuple or 2-tuple should depend on the input pattern. I don't understand why it's set based on the NIC type.

This is because i350 and 82580 nic only support 2 tuple filter,
But 82576 support 5 tuple filter.
This is list in function igb_add_del_ntuple_filter().

I mean the tuple is only related to the input.
For example, APP can input a 5-tuple pattern, driver should know it's a 5-tuple. Then the driver checks the NIC type, if it's i350, driver can return unsupported.

You've created a macro to do it in the previous patch, why not use the macro? The same below.

Yes, maybe I should use NEXT_ITEM_OF_PATTERN(item, pattern, index) to replace it in v3.

Is a copy necessary? Could "ntuple_filter_ptr->filter_info" be used directly for deleting?

The patches mainly finish following functions:
1) Store and restore all kinds of filters.
2) Parse all kinds of filters.
3) Add flow validate function.
4) Add flow create function.
5) Add flow destroy function.
6) Add flow flush function.
v2 changes:
fix git log warning
rebase patch set
v3 change:
add 2_tuple filter check for too many parameters
change style of coding in igb_ntuple_filter_uninit
replace pattern check with NEXT_ITEM_OF_PATTERN
fix git log warning
