In order to prevent Tx timeout issues, toggle the netif_carrier when disabling and enabling queue pair during XSK pool setup. One of conditions checked on running in the background dev_watchdog() is netif_carrier_ok(), so let us turn it off when we disable the queues that belong to a q_vector where XSK pool is being configured.
