2017-02-14sunvnet: remove extra rcu_read_unlocksShannon Nelson
The RCU read lock is grabbed first thing in sunvnet_start_xmit_common() so it always needs to be released. This removes the conditional release in the dropped packet error path and removes a couple of superfluous calls in the middle of the code.

2017-02-14sunvnet: remove unused variable in maybe_tx_wakeupSowmini Varadhan
The vio_dring_state *dr variable is unused in maybe_tx_wakeup(). As the comments indicate, we call maybe_tx_wakeup() whenever we get a STOPPED LDC message on the port. If the queue is stopped, we want to wake it up so that we will send another START message at the next TX and trigger the consumer to drain the dring.

2017-02-14sunvnet: make sunvnet common code dynamically loadableShannon Nelson
When the sunvnet_common code was split out for use by both sunvnet and the newer ldmvsw, it was made into a static kernel library, which limits the usefulness of sunvnet and ldmvsw as loadables, since most of the real work is being done in the shared code. Also, this is simply dead code in kernels that aren't running the LDoms. This patch makes the sunvnet_common into a dynamically loadable module and makes sunvnet and ldmvsw dependent on sunvnet_common.

2017-02-14ath10k: silence firmware file probing warningsMichal Kazior
Firmware files are versioned to prevent older driver instances to load unsupported firmware blobs. This is reflected with a fallback logic which attempts to load several firmware files. This however produced a lot of unnecessary warnings sometimes confusing users and leading them to rename firmware files making things even more confusing. Hence use request_firmware_direct() which does not produce extra warnings. This shouldn't really break anything because most modern systems don't rely on udev/hotplug helpers to load firmware files anymore. For example it was confirmed that LEDE does not user helper. This also fixes a 60 second delay per _each_ unexistent firmware/calibration file with distros which have CONFIG_FW_LOADER_USER_HELPER_FALLBACK enabled, RHEL being a notable example. Using ath10k with firmware-2.bin this might end up into a five minute delay in boot.

To make it easier to handle minimum and maximum firmware API numbers convert the firmware fetch functionality to a loop.

This is needed when we switch to using request_firmware_direct() which doesn't print any errors anymore. Also add a new function for creating the fw file name dynamically which makes it easier to add new bus support, for example SDIO and USB, later.

2017-02-14ath10k: fix napi crash during rmmod when probe firmware failsKalle Valo
This fixes the below crash when ath10k probe firmware fails, NAPI polling tries to access a rx ring resource which was never allocated. An easy way to reproduce this is easy to remove all the firmware files, load ath10k modules and ath10k will crash when calling 'rmmod ath10k_pci'. The fix is to call napi_enable() from ath10k_pci_hif_start() so that it matches with napi_disable() being called from ath10k_pci_hif_stop(). Big thanks to Mohammed Shafi Shajakhan who debugged this and provided first version of the fix. In this patch I just fix the actual problem in pci.c instead of having a workaround in core.c.

This driver supports the Lantiq SSC SPI controller in master mode. This controller is found on Intel (former Lantiq) SoCs like the Danube, Falcon, xRX200, xRX300. The hardware uses two hardware FIFOs one for received and one for transferred bytes. When the driver writes data into the transmit FIFO the complete word is taken from the FIFO into a shift register. The data from this shift register is then written to the wire. This driver uses the interrupts signaling the status of the FIFOs and not the shift register. It is also possible to use the interrupts for the shift register, but they will send a signal after every word. When using the interrupts for the shift register we get a signal when the last word is written into the shift register and not when it is written to the wire. After all FIFOs are empty the driver busy waits till the hardware is not busy any more and returns the transfer status.

2017-02-14IB/mlx4: Take source GID by index from HW GID tableTalat Batheesh
Previously, we used the HW GID index in order to search the source GID in the software GID cached table. In some cases, for example when the MAC Address of the network interface is changed, the GID cached table saves the old-IPv6-link-local GID at the end of the table. When returning the old MAC address, the software GID cached table tries to add the new IPv6-link-local GID, and when it identifies that the GID already exists, the software GID cached does not add it. Thus a mismatch occurs between the HW and the SW GID tables. It resulted with sending traffic with the wrong source GID. This commit fixes the issue by taking both from the HW table. The problem can be reproduced with the following scenario: Client: # ifconfig ens6 2.2.2.5 # ifconfig ens6 inet6 add 2001:0db8:0:f101::5/64 # ifconfig ens6 hw ether f4:52:14:61:a0:71 # ifconfig ens6 inet6 del 2001:0db8:0:f101::5/64 # ifconfig ens6 inet6 add 2001:0db8:0:f101::5/64 # ucmatose -f ipv6 -b 2001:0db8:0:f101::5 -s 2001:0db8:0:f101::6 -p 20156 Server: # ucmatose -f ipv6 -b 2001:0db8:0:f101::6 -p 20156 Fixes: 4c3eb3ca1396 ('IB/mlx4: Add VLAN support for IBoE') Signed-off-by: Talat Batheesh <talatb@mellanox.com> Reviewed-by: Maor Gottlieb <maorg@mellanox.com> Signed-off-by: Leon Romanovsky <leon@kernel.org> Signed-off-by: Doug Ledford <dledford@redhat.com>

2017-02-14IB: Query ports via the core instead of direct into the driverOr Gerlitz
Change the drivers to call ib_query_port in their get port immutable handler instead of their own query port handler. Doing this required to set the core cap flags of this device before the ib_query_port call is made, since the IB core might need these caps to serve the port query. Drivers are ensured by the IB core that the port attributes passed to the port query verb implementation are zero, and hence we removed the zeroing from the drivers. This patch doesn't add any new functionality.
