qeth: support z/VM VSWITCH Port Isolation z/VM Virtual Switch Port Isolation allows guests on a VLAN UNAWARE virtual switch to be isolated from other guests on the VSWITCH. (See z/VM Apars VM64281 and VM64463). The Linux qeth driver is affected, because it has to handle new error codes introduced with the z/VM VSWITCH Port Isolation support.

qeth: improve ip_list administration after deregister failures 1. ip_list handling after deregister failure of multicast address: If error code "MC Address not found" is returned do not re-add multicast address to ip_list. For other error codes readd multicast address at the end of function qeth_delete_all_mc. 2. ip_list handling after deregister failure or normal ip address: If error code "IP Address not found" is returned do not re-add multicast address to ip list. This is especially important in IP address takeover scenarios, to enable re-takeover of a taken over IP address.

qeth: Support VEPA mode The existing port isolation mode 'forward' will now verify that the adjacent switch port supports the required reflective relay (RR) mode. This patch adds the required error handling for the cases where enabling port isolation mode 'forward' can now fail. Furthermore, once established, we never fall back from one of the port isolation modes to a non-isolated mode without further user-interaction. This includes cases where the isolation mode was enabled successfully, but ceases to work e.g. due to configuration changes at the switch port. Finally, configuring an isolation mode with the device being offline will make onlining the device fail permanently upon errors encountered until either errors are resolved or the isolation mode is changed by the user to a different mode.
