Hello,
I'm currently working on enabling the RTE_ETH_RX_OFFLOAD_VLAN_STRIP offload feature to strip VLAN tags and store the VLAN information in the vlan_tci field while using an Intel E810-XXVDA2 NIC. However, the VLAN tags are not being stripped. I've already tried to update DPDK (23.11), E810 firmware (4.40), ICE and DDP (1.3.35.0) but nothing. My console output is:
