RCA:
leftover OVN agents caused an issue with accessing FIP after removing the leftovers and rebooting the computes FIP works as expected 
After running adoption on NFV ENV it seems like pre-created VMs are unable to receive ping (wasn't trying new VMs yet). it seems like ovs is having issues in computes:

additional info gathered:
- ping from qdhcp netns works
- when pinging continuously ping to FIP works for some packets but most are not replied (adding a screen print)
- ping between dpdk-dut and sriov-dut (on the same compute) works across VFs and DPDK networks.
- ping on dpdk network works across computes as well (sriov-dut -> TREX)
- is related to
