LS1046 DPDK

[dah]

In the case of Layer 2 forwarding in dpdk, only IPv4 or IPv6 type packets can be received, and ARP packets cannot be received. However, ARP packets can be counted through TestPMD. Is it possible that FMAN in DPAA filters out non-IP packets?

[yipingwang]

We have verified that the ARP packets can be forwarded by the DPDK application l2fwd.
