Hi Stephen,

Downloaded https://fast.dpdk.org/rel/dpdk-22.11.1.tar.xz, built and linked
with the application. Still don't get rxq interrupt of ixgbe ports.

EAL: Detected CPU lcores: 4
EAL: Detected NUMA nodes: 1
EAL: Detected static linkage of DPDK
EAL: Multi-process socket /var/run/dpdk/rte/mp_socket
EAL: Selected IOVA mode 'PA'
EAL: VFIO support initialized
EAL: Using IOMMU type 8 (No-IOMMU)
EAL: Probe PCI driver: net_ixgbe (8086:15e4) device: 0000:02:00.0 (socket

EAL: Probe PCI driver: net_ixgbe (8086:15e4) device: 0000:02:00.1 (socket

EAL: Ignore mapping IO port bar(2)

#>>>>> igb port irq counter is non-zero (likely to be rxq), where-as the
same for ixgbe is 0.
