    net: fix network drivers ndo_start_xmit() return values (part 7)
    
    Fix up ATM drivers that return an errno value to qdisc_restart(), causing
    qdisc_restart() to print a warning an requeue/retransmit the skb.
    
    - lec: condition can only be remedied by userspace, until that retransmissions
    
    Compile tested only.
