Maciej Fijalkowski 6c7273a266 ixgbe: xsk: change !netif_carrier_ok() handling in ixgbe_xmit_zc() ... Commit c685c69fba ("ixgbe: don't do any AF_XDP zero-copy transmit if netif is not OK") addressed the ring transient state when MEM_TYPE_XSK_BUFF_POOL was being configured which in turn caused the interface to through down/up. Maurice reported that when carrier is not ok and xsk_pool is present on ring pair, ksoftirqd will consume 100% CPU cycles due to the constant NAPI rescheduling as ixgbe_poll() states that there is still some work to be done. To fix this, do not set work_done to false for a !netif_carrier_ok().
