2017-05-30net: qualcomm: rename qca_framing.c to qca_7k_common.cStefan Wahren5-4/+4
As preparation for the upcoming UART driver we need a module which contains common functions for both interfaces. The module qca_framing is a good candidate but renaming to qca_7k_common would make it clear. Signed-off-by: Stefan Wahren <stefan.wahren@i2se.com> Signed-off-by: David S.

2017-05-30nfp: don't wait for resources indefinitelyJakub Kicinski3-4/+20
There is currently no timeout to the resource and lock acquiring loops. We printed warnings and depended on user sending a signal to the waiting process to stop the waiting. This doesn't work very well when wait happens out of a work queue. The simplest example of that is PCI probe. When user loads the module and card is in a broken state modprobe will wait forever and signals sent to it will not actually reach the probing thread. Make sure all wait loops have a time out. Set the upper wait time to 60 seconds to stay on the safe side. Signed-off-by: Jakub Kicinski <jakub.kicinski@netronome.com> Signed-off-by: David S. Miller <davem@davemloft.net>

We want to support extendable commands, where newer versions of the management FW may provide more information. Zero out the communication buffer before passing control to NSP.

2017-05-30nfp: support long reads and writes with the cpp helpersJakub Kicinski2-18/+72
nfp_cpp_{read,write}() helpers perform device memory mapping (setting the PCIe -> NOC translation BARs) and accessing it. They, however, currently implicitly expect that the length of entire operation will fit in one BAR translation window. There is a number of 16MB windows available, and we don't really need to access such large areas today. If the user, however, manages to trick the driver into making a big mapping (e.g. by providing a huge fake FW file), the driver will print a warning saying "No suitable BAR found for request" and a stack trace - which most users find concerning. To be future-proof and not scare users with warnings, make the nfp_cpp_{read,write}() helpers do accesses chunk by chunk if the area size is large. Set the notion of "large" to 2MB, which is the size of the smallest BAR window. Signed-off-by: Jakub Kicinski <jakub.kicinski@netronome.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-05-30nfp: only try to get to PCIe ctrl memory if BARs are wide enoughJakub Kicinski1-2/+8
For accessing PCIe ctrl memory we depend on the BAR aperture being large enough to reach all registers.

2017-05-30nfp: don't set aux pointers if ioremap failedJakub Kicinski1-8/+12
If ioremap of PCIe ctrl memory failed we can still get to it through PCI config space, therefore we allow ioremap() to fail. When if fails, however, we must leave all the IOMEM pointers as NULL. Currently we would calculate csr and em pointers, adding offsets to the potential NULL value and therefore making the NULL-checks throughout the code ineffective.

2017-05-30nfp: set driver VF limitJakub Kicinski1-8/+15
PCI subsystem has support for drivers limiting the number of VFs available below what the IOV capability claims. Make use of it. While at it remove the #ifdef/#endif on CONFIG_PCI_IOV, it was there to avoid unnecessary warnings in case device read failed but kernel doesn't have SR-IOV support anyway. Device reads should not fail. Note that we still need the driver-internal check for the case where max VFs is 0 since PCI subsystem treats 0 as limit not set.

2017-05-28net: phy: Relax error checking on sysfs_create_link()Florian Fainelli1-8/+22
Some Ethernet drivers will attach/connect to a PHY device before calling register_netdevice() which is responsible for calling netdev_register_kobject() which would do the network device's kobject initialization. In such a case, sysfs_create_link() would return -ENOENT because the network device's kobject is not ready yet, and we would fail to connect to the PHY device. In order to keep things simple and symetrical, we just take the success path as indicative of the ability to access the network device's kobject, and create the second link if that's the case.

2017-05-28bonding: Prevent duplicate userspace notificationVlad Yasevich2-3/+27
Whenever a user changes bonding options, a NETDEV_CHANGEINFODATA notificatin is generated which results in a rtnelink message to be sent. While runnig 'ip monitor', we can actually see 2 messages, one a result of the event, and the other a result of state change that is generated bo netdev_state_change(). However, this is not always the case. If bonding changes were done via sysfs or ifenslave (old ioctl interface), then only 1 message is seen. This patch removes duplicate messages in the case of using netlink to configure bonding. It introduceds a separte function that triggers a netdev event and uses that function in the syfs and ioctl cases. This was discovered while auditing all the different envents and continues the effort of cleaning up duplicated netlink messages.
