[dpdk-stable] [PATCH v2] ip_frag: fix fragmenting IPv4 fragment

[蔡慧超]

Hi,Konstantin


I'm glad to receive your ack！


Follow the documentation 《Contributing Code to DPDK》：
1.Update Patchwork to mark your previous patches as “Superseded”.
--Who is responsible for this update, I just tried, prompt no permission update(
You don't have permissions to edit patch 'ip_frag: modify the fragment offset and mf').


2.Note: When acking patches please remove as much of the text of the patch email as possible. 
It is generally best to delete everything after the Signed-off-by: line.
--Does this require me to send another patch email?And the content is like this:


Current implementation of rte_ipv4_fragment_packet() doesn’t take
into account offset and flag values of the given packet, but blindly
assumes they are always zero (original packet is not fragmented).
According to RFC791, fragment and flag values for new fragment
should take into account values provided in the original IPv4 packet.


Fixes: 4c38e5532a07 ("ip_frag: refactor IPv4 fragmentation into a proper library")
