                                              ^^^^
Note the zero initialization here.

Should this be zero-initialized with = {} like the other similar
functions in this file (hinic3_set_rx_lro, hinic3_set_rx_lro_timer,
hinic3_set_rx_vlan_offload)?

When hinic3_send_mbox_to_mgmt() fails, vlan_filter.msg_head.status
contains garbage which is then printed in the dev_err() message below.
Additionally, the uninitialized rsvd[2] and msg_head fields are sent to
the firmware in the mailbox message.
