    realtek: rtl93xx: Send per port packets on physical port
    
    If link aggregation with LACP is activated, we must send out the LACP
    packets on the physical port and not on a logic port. Otherwise, the per
    port packets might be (rebalanced) between the different ports in a link
    aggregation group.
    
    Such rebalancing breaks 802.3ad and will leave ports in a churned state.
