parent[TG3]: Remove unnecessary tx_lock (diff)
[TG3]: Convert to non-LLTX
Herbert Xu pointed out that it is unsafe to call netif_tx_disable() from LLTX drivers because it uses dev->xmit_lock to synchronize whereas LLTX drivers use private locks. Convert tg3 to non-LLTX to fix this issue. tg3 is a lockless driver where hard_start_xmit and tx completion handling can run concurrently under normal conditions. A tx_lock is only needed to prevent netif_stop_queue and netif_wake_queue race condtions when the queue is full. So whether we use LLTX or non-LLTX, it makes practically no difference.
