If the watchdog timer fires while the queues are stopped and traffic has not recently been sent on a paticular queue this is falsly identified as a hang and ndo_tx_timeout() is called. This is ocossionally seen during testing. This removes the netif_tx_stop_all_queues() it is not needed. The scheduler submits skb's with dev_hard_start_xmit(), this checks if netif_needs_gso and if so it calls dev_gso_segment. Disabling TSO will cause dev_hard_start_xmit() to do the gso processing. However ixgbe does not use the features flags to determine if it needs to use tso or not instead it uses skb->gso_size so ixgbe will process these frames correctly regardless of the netdev features flag.
