ip_frag: add IPv4 fragment copy
Some NIC drivers support MBUF_FAST_FREE (device supports optimization for fast release of mbufs. When set, application must guarantee that per-queue all mbufs comes from the same mempool, has refcnt = 1, direct and non-segmented.) offload.
In order to adapt to this offload function, add this API. Add some test data for this API.

Status|RESOLVED |CONFIRMED--- Comment #2 from Ferruh YIGIT ([email protected]) --- Hi Daxue,
The problem is neither related to the compiler version nor the commit listed above, it should be related to the kernel version.
The related build error fixed in commit:c98600d4bed6 ("kni: fix build with Linux 5.18")
Starting with kernel version 5.18, 'netif_rx_ni()' function is removed from kernel.
Having a build error with RHEL9.0/5.14.0-160.el9.x86_64 kernel means it backported related kernel commit.
So, I expect the issue is still valid and it needs a special RHEL version check in KNI.
Can you please double check with RHEL9 again?
