Alexandra Winter 7a07a29e4f s390/qeth: cache link_info for ethtool ... Since commit e6e771b3d8 ("s390/qeth: detach netdevice while card is offline") there was a timing window during recovery, that qeth_query_card_info could be sent to the card, even before it was ready for it, leading to a failing card recovery. There is evidence that this window was hit, as not all callers of get_link_ksettings() check for netif_device_present. Use cached values in qeth_get_link_ksettings(), instead of calling qeth_query_card_info() and falling back to default values in case it fails. Link info is already updated when the card goes online, e.g. after STARTLAN (physical link up). Set the link info to default values, when the card goes offline or at STOPLAN (physical link down). A follow-on patch will improve values reported for link down.
