Bug ID: 1868
Summary: bnxt: RTE_MBUF_F_RX_VLAN_STRIPPED set but vlan_tci is
0
Product: DPDK
Version: 26.03
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: ethdev
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
BCM957608-P2100GQF20 (235.1.157.0) with TruFlow disabled (via niccli) and
RTE_ETH_RX_OFFLOAD_VLAN_STRIP enabled doesn't set vlan_tci - it always remains
0, even though the VLAN itself is removed from the packet, and
RTE_MBUF_F_TX_VLAN and RTE_MBUF_F_RX_VLAN_STRIPPED flags are set.
- With testpmd, vlan_tci is 0 as well, type is 0x8000, so vlan is not there
anymore.

- If I do "port config 0 rx_offload vlan_strip off" RTE_MBUF_F_RX_VLAN_STRIPPED
added anyway, even though the type is 0x8100, so vlan wasn't stripped.
