Commit efc73f4b "net: Fix memory leak - vlan_info struct" adds deletion of VLAN 0 for devices with feature NETIF_F_HW_VLAN_FILTER. For driver qeth these are the layer 3 devices. Usually there exists no separate vlan net_device for VLAN 0. Thus the qeth functions qeth_l3_free_vlan_addresses4() and qeth_l3_free_vlan_addresses6() require an extra checking if function __vlan_find_dev_deep() returns with a net_device.

Remove the file name from the comment at top of many files. In most cases the file name was wrong anyway, so it's rather pointless. Also unify the IBM copyright statement. We did have a lot of sightly different statements and wanted to change them one after another whenever a file gets touched. However that never happened. Instead people start to take the old/"wrong" statements to use as a template for new files. So unify all of them in one go. Signed-off-by:Heiko Carstens <heiko.carstens@de.ibm.com>

The qeth layer3 driver is notified about IP address changes. Changes concerning qeth driven network interfaces have to be forwarded to the OSA-card. This includes IP addresses of VLAN interfaces with a qeth device as base device. Function qeth_l3_verify_vlan_dev() determines if the net_device of the IP event belongs to a vlan device belonging to a qeth device as real device. This function is broken starting with commit 7ff0bcf6 , which means IP addresses of VLAN devices are no longer set at the base qeth device. The patch repairs function qeth_l3_verify_vlan_dev().

We've moving to a model where dst_entry objects to not have a reference to the associated neighbour entry, instead such neighbours must be looked up on-demand. Here in qeth_l3_fill_header() it's actually much simpler to use the information in the route itself. The code is already conditionalized upon protocol type. Signed-off-by:

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. Signed-off-by: -

The open function of qeth is not executed if the qeth device is in state DOWN or HARDSETUP. A recovery switches from state SOFTSETUP to HARDSETUP to DOWN to HARDSETUP and back to SOFTSETUP. If open and recover are running concurrently, open fails if it hits the states HARDSETUP or DOWN. This patch inserts waiting for recovery finish in the qeth open functions to enable successful qeth device opening in spite of a running recovery. Signed-off-by:

Device initialization of a qeth device contains a STARTLAN step. This step may fail, if cable is not yet plugged in. The qeth device stays in state HARDSETUP until cable is plugged in. This prevents further preparational initialization steps of the qeth device and its network interface. This patch makes sure initialization of qeth device continues, even though cable is not yet plugged in. Once carrier is available, qeth is notified, triggers a recovery which results in a working network interface. Signed-off-by:
