If a default VLAN is enabled, the VF cannot support VLAN acceleration on the receive side and the VNIC must be setup to strip out the default VLAN tag. If a default VLAN is not enabled, the VF can support VLAN acceleration on the receive side. The VNIC should be set up to strip or not strip the VLAN based on the RX VLAN acceleration setting. Without this call to determine the default VLAN before calling bnxt_setup_vnic(), the VNIC may not be set up correctly. For example, bnxt_setup_vnic() may set up to strip the VLAN tag based on stale default VLAN information. If RX VLAN acceleration is not enabled, the VLAN tag will be incorrectly stripped and the RX data path will not work correctly.

Implementing the current .udp_tunnel_sync callback would mean that the deleted tunnel port entry would be all zeros. This used to work on older firmware because it would not check the input when deleting a tunnel port. With newer firmware, the delete will now fail and subsequent tunnel port allocation will fail as a result.
