s390: Use pr_warn instead of pr_warning

2016-03-07T12:12:04+00:00

Convert the uses of pr_warning to pr_warn so there are fewer uses of the old pr_warning. Miscellanea: o Align arguments o Coalesce formats Signed-off-by: Joe Perches Signed-off-by: Heiko Carstens Signed-off-by: Martin Schwidefsky

qeth: get rid of redundant 0-termination

2015-12-14T21:16:45+00:00

0-termination is redundant, since sprintf has done that. Signed-off-by: Rasmus Villemoes Signed-off-by: Ursula Braun Signed-off-by: David S. Miller

qeth: repair SBAL elements calculation

2015-12-14T21:16:45+00:00

When sending skbs, qeth determines the number of qdio SBAL elements required. If qeth sends a fragmented skb, the SBAL element number calculation is wrong, because the fragmented data part is added twice in qeth_l3_tso_elements(). This patch makes sure fragmented data is handled in qeth_elements_for_frags() only, while qeth_l3_tso_elements() starts calculation of qdio SBAL elements just with the linear data part of the skb.

qeth: initialize net_device with carrier off

2015-12-14T21:16:45+00:00

/sys/class/net//operstate for an active qeth network interface offen shows "unknown", which translates to "state UNKNOWN in output of "ip link show". It is caused by a missing initialization of the __LINK_STATE_NOCARRIER bit in the net_device state field. This patch adds a netif_carrier_off() invocation when creating the net_device for a qeth device.

qeth use common function qeth_get_setassparms_cmd

2015-12-14T21:16:45+00:00

There have been 2 identical versions of function qeth_get_setassparms_cmd() for layer 2 and layer 3. Remove the layer 3 function qeth_l3_get_setassparms_cmd() and call the common one named qeth_get_setassparms_cmd() located in qeth_core_main.c Signed-off-by: Thomas Richter Signed-off-by: Ursula Braun Reviewed-by: Eugene Crosser Signed-off-by: David S.

s390-ctcm: Delete unnecessary checks before the function call "channel_remove"

2015-12-14T21:16:44+00:00

The channel_remove() function tests whether its argument is NULL and then returns immediately. Thus the test around the calls is not needed. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring Signed-off-by: Ursula Braun Signed-off-by: David S. Miller

s390/qeth: optimize MAC handling in rx_mode callback

2015-10-07T11:52:04+00:00

In layer2 mode of the qeth driver, MAC address lists from struct net_device require mapping to the OSA-card. The existing implementation is inefficient for lists with more than several MAC addresses, since for every ndo_set_rx_mode callback it removes all MAC addresses first, and then registers the current MAC address list. This patch changes implementation of ndo_set_rx_mode callback in qeth, only performing hardware registration/removal for new/deleted addresses. To shorten lookup of MAC addresses registered addresses are kept in a hashtable instead of a linear list.

s390/qeth: switch to napi_gro_receive

2015-10-07T11:52:04+00:00

Add support for GRO (generic receive offload) in the layer 2 part of device driver qeth. This results in a performance improvement when GRO and RX is turned on. Signed-off-by: Thomas Richter Signed-off-by: Ursula Braun Signed-off-by: David S. Miller

s390/iucv: do not use arrays as argument

2015-09-21T23:03:04+00:00

The iucv code uses arrays as arguments. Even though this does not really cause a problem, it could be misleading, since the compiler turns array arguments into just a pointer argument. To be more precise this patch changes the array arguments into pointers. Signed-off-by: Ursula Braun Signed-off-by: David S. Miller

qeth: add layer 2 RX/TX checksum offloading

2015-09-21T23:03:04+00:00

Checksum offloading for send and receive is already supported for layer 3 (IP layer). This patch adds support for RX and TX hardware checksum offloading for layer 2 (MAC layer). The hardware calculates the checksum for IP UDP and TCP packets. This patch moves the hardware checksum offloading setup to the set of common functions in qeth_core_main.c. Layer 2 and layer 3 now simply call the same common functions. Also note that TX checksum offloading is always enabled. The device driver relies on the TCP/IP stack to make use of this feature.
