TTL decrement for traffic between two AntreaIPAM Pods running on same Node and in same subnet.

[Atish-iaf]

Describe the bug
TTL decrement by 1 for traffic between two AntreaIPAM Pods running on same Node and in same subnet(Node subnet, VLAN=0).
TTL gets decremented in OVS L3DecTTL table.

To Reproduce
Create IPPool, allocate IP ranges from node subnet(VLAN=0).
Create 2 antreaipam pods having IP from above created IPPool and schedule both pods on same node.
Ping between these 2 pods.

Expected
TTL shouldn't decrement.

Actual behavior
TTL gets decremented by 1.

Versions:

• agentVersion: 2.3.0-dev-2773cfd61

Additional context
In the screenshot below, 172.18.0.0/16 is node subnet, 10.244.2.0/24 is NodeIPAM PodCIDR for kind-worker Node.
