For example,\nif the VNICC flooding is configured on a qeth device, ethernet frames to\nunknown destination MAC addresses are received.\n\nCurrently, there is support for seven VNICCs: flooding, multicast\nflooding, receive broadcast, learning, takeover learning, takeover\nsetvmac, bridge invisible. Also, six IPA commands exist for configuring\nVNICCs on a qeth device: query characteristics, query commands, enable\ncharacteristic, disable characteristic, set timeout, get timeout.\n\nThis patch adds the basic code infrastructure for VNICC support to qeth.\nIt allows querying VNICC support from the underlying hardware. To this\nend, it adds:\n\n* basic message formats for IPA commands\n* basic data structures\n* basic error handling\n* query characteristics IPA command support\n\nThe query characteristics IPA command allows requesting the currently\nsupported and currently enabled VNIC characteristics from the underlying\nhardware.\n\nSupport for the other IPA commands and for the configuration of VNICCs\nis added in follow-up patches together with the respective user\ninterface functions.\n\nSigned-off-by: Hans Wippel <hwippel@linux.vnet.ibm.com>\nReviewed-by: Julian Wiedmann
