Hi,
How does ODP handles the vlan header removal in accordance to
vlan-rx-offload feature in linux/hardware?
Are there any APIs for:
1. To know if vlan header is removed, if the offload feature is set or
not?
2. What is the vlan value if the HDR is removed?
3. How to set/unset the vlan
I have a simple *standalone application* using ODP. It receives packets on
one interface and do a broadcasting to all other interfaces. But many a
times i see this error message when i try to calculate the throughput using
IPerf tool.
pktio/socket_mmap.c:263:pkt_mmap_v2_tx():sendto(pkt m
I am using the linux-generic with ODP v1.9.0.0
I am just running Iperf with default settings.
But i will try similar experiments by turning off the segment offloading on the
target NIC. Thank you for the pointer.

I encountered an old email chain about the different LPM algorithm for ODP.
I am curious if anyone has released or working on something for l3
forwarding/routing.
Here is the link to the mail chain:

Hi,
I am unable to find the cuckoo hash files in the recent code base. Is the
feature is removed from ODP code base or renamed to something else?
Thank you

equisites details? I am using the latest master branch of ODP.

There is no link available for the "Cavium implementation" by Support Account
on the ODP download page. How can i have access to the code and also
corresponding toolchain if needed?

Hi All,
I have seen ODP and SAI have good traction in networking community with
very rapid contribution and development. Can anyone please explain how they
are different from each other? What is the fundamental difference in their

Hi,
I am trying to run ODP & ODP-DPDK examples on our server with mellanox 100G
NICs. I am using the odp_l2fwd example. While running the example, I am
facing some issues.
-> When I run "ODP" example using the if names given by kernel as
arguments, I am not getting enough throughput.(the value is v
dpdk too.
Is there anything i am missing?

I have noticed that ODP application always check for hugepages and fails

does, how can i make sure that ODP application uses the hugepages???

ODP with netmap.
I run example/l2-load-latency.lua from moongen and odp_l2fwd_simple from
