Hello, Please what is the relation between NIC ring sizes and XDP socket ring sizes? If my app sets XDP_RX_RING and XDP_TX_RING, what are the optimal values for ethtool -G rx/tx? Also I don't understand why changing TX ring size changes some XDP ring size for the ice driver (Kernel 5.13): [ 424.542118] ice 0000:41:00.0 enp65s0f0: Changing Tx descriptor count from 256 to 2048 [ 424.542176] ice 0000:41:00.0 enp65s0f0: Changing XDP descriptor count from 256 to 2048 <- What is that? In the case of the i40e driver, there is no XDP ring logged: [847243.925269] i40e 0000:81:00.0 enp129s0f0: Changing Tx descriptor count from 256 to 2048. Thank you, Daniel
