Seeing the issue on Netronome testbed with acceleration enabled. Without acceleration, the issue is not observed.
Steps to recreate the issue:
1) Create a VN vn1
2) enable ip forwarding in vn1
Subnet(s)
CIDR Gateway Service Address DNS DHCP Allocation Pools
30.238.247.0/24 30.238.247.1 30.238.247.2 Enabled Enabled -
IP Fabric Forwarding Enabled
2) Launch 2 VMs in VN1
Ping from vm1 to vm2 and expect ping to work.
Observations:
1) Ping not working when gwless (ip fabric forwarding ) and netronome acceleration is enabled

Seeing the issue on Netronome testbed with acceleration enabled. Without acceleration, the issue is not observed.
Steps to recreate the issue:
1) Create a VN vn1
2) enable ip fabric forwarding in vn1
Subnet(s)
CIDR Gateway Service Address DNS DHCP Allocation Pools
30.238.247.0/24 30.238.247.1 30.238.247.2 Enabled Enabled -
IP Fabric Forwarding Enabled
2) Launch 2 VMs in VN1
Ping from vm1 to vm2 and expect ping to work.
Observations:
1) Ping not working when gwless (ip fabric forwarding ) and netronome acceleration is enabled

TEST : test_gw_less_fwd_single_vn_ip_fab
Test Gateway less forwarding with single VN and IP Fabric provider
network. IP Fbaric network is configured as provider network
over vn1. Multiple VMs will be launched across compute nodes
and ping between VMs should be successful and happen through
underlay. Ping between vhosts to VMs should be successful and happen
through underlay. Also, ping between VMs to vhosts also should be
successful and should go through underlay.
