That is incorrect and will trigger null-ptr-deref\nfor vlan->real_dev in vlan_dev_hard_header() because team device is not\na vlan device.\n\nCache eth_header_ops in team_setup(), then assign cached header_ops to\nheader_ops of team net device when its type is changed from non-ether\nto ether to fix the bug."
