Whenever user changes interface MAC address both default DMAC based MCAM rule and VLAN offload (for strip) rules are updated with new MAC address. To update or install VLAN offload rule PF driver needs interface's receive channel info, which is retrieved from admin function at the time of NIXLF initialization. If user changes MAC address before interface is UP, VLAN offload rule installation will fail and throw error as receive channel is not valid. To avoid this, skip VLAN offload rule installation if netdev is not UP. This rule will anyway be reinslatted as part of open() call.
