If hardware VLAN offload is in use, this existing filter table would also be cleared. Instead, setup the shadow table once during device initialization and just update during restart. vmxnet3_dev_vlan_offload_set(dev, mask) was incorrectly treating the mask parameter as the bitmask for vlan_strip and vlan_filter, whereas the mask indicates only what has changed - the values for vlan_stripping and vlan_filter needs to be taken from dev_conf.rxmode.
