Increase the default TX ring size (from 512 to 1024) to match the RX ring size. This gives the XDP TX ring a better chance to keep up with the rate of its RX ring in case of a high load of XDP_TX actions. Tested: Ethtool counter rx_xdp_tx_full used to increase, after applying this patch it stopped.
