netif_tx_start_all_queues is used to allow the upper layer
to transmit frames but it does not restart transmission.
To restart the trasmission use netif_tx_wake_all_queues.
Not doing so, sometimes stalls the transmission and the
application has to be restarted to proceed further.

This issue was originally found while sending udp traffic
in higer bandwidth in open environment without bgscan.
