From: Kamil Maziarz <kamil.maziarz@xxxxxxxxx>
Avoid stopping netdev tx queues during XSK setup by removing
netif_tx_stop_queue() and netif_tx_start_queue().
These changes prevent unnecessary stopping and starting of netdev
transmit queues during the setup of XDP socket. Without this change,
after stopping the XDP traffic flow tracker and then stopping
the XDP prog - NETDEV WATCHDOG transmit queue timed out appears.
