Hi All,
We were trying to test the vlan filter with Melloanox
nic(SR-IOV) on VmWare using the mlx5_pmd. But found that after doing the
mlx5_vlan_filter_set with the vlan id also, we are not receiving the tagged
packets upto the application. The same works fine in we are using KVM as the
hypervisor. To check if this the PF deiver issue, we removed the dpdk and made
the vlan config on the linux interface and then found that the tagged packets
are coming upto the VM. Moreover the same tag which was used by linux kernel
keeps working with DPDK too even after reboot o the VM but new tags added
through DPDK does not work . Is it necessary to add the tags every time to the
linux netdev before using it through dpdk ? Though this does not sound
right.Can somebody help me in why with dpdk we are not able to receive the
tagged packets ?
DPDK version : 18.11.6
ESXi : 7.0
NICs : Mellanox Cx-4
Just to summarize :
1. VLAN filter add through DPDK works fine with KVM hypervisor.
2. VLAN filter add through DPDK on VmWare does not work.
3. VLAN add through linux netdev works fine on VmWare
4. VLAN once added on the linux netdev, even after eboot the same VLAN added
through dpdk works fine on VmWare. Any new VLAN added through dpdk does not
work.
