fjes: fix missed check in fjes_acpi_add

2019-12-31T15:34:36+00:00

[ Upstream commit a288f105a03a7e0e629a8da2b31f34ebf0343ee2 ] fjes_acpi_add() misses a check for platform_device_register_simple(). Add a check to fix it.

fjes: Handle workqueue allocation failure

2019-11-12T18:21:12+00:00

[ Upstream commit 85ac30fa2e24f628e9f4f9344460f4015d33fd7d ] In the highly unlikely event that we fail to allocate either of the "/txrx" or "/control" workqueues, we should bail cleanly rather than blindly march on with NULL queue pointer(s) installed in the 'fjes_adapter' instance.

fjes: use currently unused variable my_epid and max_epid

2018-07-05T10:34:21+00:00

Variables my_epid and max_epid are currently assigned and not being used - however, I suspect they were intended to be used in the for-loops to reduce the dereferencing of hw. Replace hw->my_epid and hw->max_epid with these variables. Cleans up clang warnings: warning: variable 'my_epid' set but not used [-Wunused-but-set-variable] variable 'max_epid' set but not used [-Wunused-but-set-variable] Signed-off-by: Colin Ian King Signed-off-by: David S.

networking: introduce and use skb_put_data()

2017-06-16T15:48:37+00:00

A common pattern with skb_put() is to just want to memcpy() some data into the new space, introduce skb_put_data() for this. An spatch similar to the one for skb_put_zero() converts many of the places using it: @@ identifier p, p2; expression len, skb, data; type t, t2; @@ ( -p = skb_put(skb, len); +p = skb_put_data(skb, data, len); | -p = (t)skb_put(skb, len); +p = skb_put_data(skb, data, len); ) ( p2 = (t2)p; -memcpy(p2, data, len); | -memcpy(p, data, len); ) @@ type t, t2; identifier p, p2; expression skb, data; @@ t *p; ... ( -p = skb_put(skb, sizeof(t)); +p = skb_put_data(skb, data, sizeof(t)); | -p = (t *)skb_put(skb, sizeof(t)); +p = skb_put_data(skb, data, sizeof(t)); ) ( p2 = (t2)p; -memcpy(p2, data, sizeof(*p)); | -memcpy(p, data, sizeof(*p)); ) @@ expression skb, len, data; @@ -memcpy(skb_put(skb, len), data, len); +skb_put_data(skb, data, len); (again, manually post-processed to retain some comments) Reviewed-by: Stephen Hemminger Signed-off-by: Johannes Berg Signed-off-by: David S.

Remove unnecessary setting of flag IFF_BROADCAST, since ether_setup already does this. Signed-off-by: Zhang Shengju Signed-off-by: David S. Miller

fjes: Do not load fjes driver if extended socket device is not power on.

2017-03-22T19:38:17+00:00

The extended device socket cannot turn on/off while system is running. So when system boots up and the device is not power on, the fjes driver does not need be loaded. To check the status of the device, the patch adds ACPI _STA method check. Signed-off-by: Yasuaki Ishimatsu CC: Taku Izumi Signed-off-by: David S. Miller

fjes: Do not load fjes driver if system does not have extended socket device.

2017-03-22T19:38:17+00:00

The fjes driver is used only by FUJITSU servers and almost of all servers in the world never use it. But currently if ACPI PNP0C02 is defined in the ACPI table, the following message is always shown: "FUJITSU Extended Socket Network Device Driver - version 1.2 - Copyright (c) 2015 FUJITSU LIMITED" The message makes users confused because there is no reason that the message is shown in other vendor servers. To avoid the confusion, the patch adds a check that the server has a extended socket device or not. Signed-off-by: Yasuaki Ishimatsu CC: Taku Izumi Signed-off-by: David S. Miller

fjes: Fix wrong netdevice feature flags

2017-03-15T19:43:23+00:00

This patch fixes netdev->features for Extended Socket network device. Currently Extended Socket network device's netdev->feature claims NETIF_F_HW_CSUM, however this is completely wrong. There's no feature of checksum offloading. That causes invalid TCP/UDP checksum and packet rejection when IP forwarding from Extended Socket network device to other network device. NETIF_F_HW_CSUM should be omitted. Signed-off-by: Taku Izumi Signed-off-by: David S. Miller

net: fjes: use new api ethtool_{get|set}_link_ksettings

2017-03-13T02:28:07+00:00

The ethtool api {get|set}_settings is deprecated. We move this driver to new api {get|set}_link_ksettings. As I don't have the hardware, I'd be very pleased if someone may test this patch. Signed-off-by: Philippe Reynes Signed-off-by: David S. Miller
