DPDK test PMD is throwing error when trying to configure 1-4094 vlans to the interfaces (NIC - ConnectX-6 LX, 26.44.1036), everything works upto vlan 128 and start failing afterwards.
Error: failed to add vlan 129 to port 2 PMD: rte_eth_dev_vlan_filter(129) returned cannot allocate memory)
Base OS - Debian 12
DPDK Version - 22.11.8
Question : Is there any limit of 128 vlan filters on this NIC or there is any other settings I may be missing.
