Hello Ferruh,
1. Current dpdk framework provide software GRO feature, but do not
support hardware GRO offload. and it now can only process tcp4 and
vxland_tcp4 streams.
2. HNS3's hardware 1620(ARM SoC) support hardware GRO offload, it
can process tcp4 and tcp6 streams.
3. linux kernerl driver support hardware GRO feature already (named
rx-gro-hw).
so my questions:
1. Can dpdk framework have plan to support hardware GRO offload?
2. If we make this patch, could it upstream?
Regards,
Chengwen

Hi Chengwen,
cc'ed ethdev maintainers.
Can't you use LRO [1] for HW GRO offload?
