2018-06-01s390/qeth: free netdevice when removing a cardJulian Wiedmann3-4/+2
commit 6be687395b3124f002a653c1a50b3260222b3cd7 upstream. On removal, a qeth card's netdevice is currently not properly freed because the call chain looks as follows: qeth_core_remove_device(card) lx_remove_device(card) unregister_netdev(card->dev) card->dev = NULL !!! qeth_core_free_card(card) if (card->dev) !!! free_netdev(card->dev) Fix it by free'ing the netdev straight after unregistering. This also fixes the sysfs-driven layer switch case (qeth_dev_layer2_store()), where the need to free the current netdevice was not considered at all. Note that free_netdev() takes care of the netif_napi_del() for us too.

2018-06-01s390/qeth: fix SETIP command handlingJulian Wiedmann2-6/+13
commit 1c5b2216fbb973a9410e0b06389740b5c1289171 upstream. send_control_data() applies some special handling to SETIP v4 IPA commands. But current code parses *all* command types for the SETIP command code. Limit the command code check to IPA commands.

2016-08-23qeth: delete napi struct when removing a qeth deviceUrsula Braun2-0/+2
commit 7831b4ff0d926e0deeaabef9db8800ed069a2757 upstream. A qeth_card contains a napi_struct linked to the net_device during device probing. This struct must be deleted when removing the qeth device, otherwise Panic on oops can occur when qeth devices are repeatedly removed and added.

2011-08-13qeth: add support for af_iucv HiperSockets transportFrank Blaschka6-61/+391
This patch extends the HiperSockets device driver to send and receive af_iucv traffic over HiperSockets transport. TX: Driver uses new asynchronous delivery of storage blocks to pass flow control/congestion information from the HiperSockets microcode to the af_iucv socket. RX: Memory for incoming traffic is preallocated and passed to HiperSockets layer. If receiver is not capable to clean its buffers shared with HiperSockets and pass new memory to the HiperSockets layer this will cause flow control/congestion events on the sender.
