Hi i40e maintainers,
I have the following configuration:
- host runs with Linux pf i40e driver
- guest runs with DPDK vf i40e driver
I send a vlan packet from the host to the guest.
On the guest, I start testpmd with --disable-hw-vlan-strip.
When I receive the packet on the guest, it has the PKT_RX_VLAN_STRIPPED
flag although I'm not asking for it. From what I understand, it is not
possible to disable vlan stripping when using a Linux PF driver.
Since the i40evf DPDK driver does not behave like what the application
asks for, I think it should be fixed. What do you think about re-adding
the vlan in software when dev_conf->rxmode.hw_vlan_strip == 0 ?
The other alternative would be to forbid this configuration and return
an error.
Any opinion? Shall I send a patch?
Thanks
Olivier
