2016-08-20ixgbe: add support for geneve Rx offloadEmil Tantilov
Add geneve Rx offload support for x550em_a. The implementation follows the vxlan code with the lower 16 bits of the VXLANCTRL register holding the UDP port for VXLAN and the upper for Geneve. Disabled NFS filters in the RFCTL register which allows us to simplify the check for VXLAN and Geneve packets in ixgbe_rx_checksum(). Removed vxlan from the name of the callback functions and replaced it with udp_tunnel which is more in line with the new API.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue Jeff Kirsher says: ==================== 40GbE Intel Wired LAN Driver Updates 2016-08-19 This series contains updates to i40e and i40evf only. Jake provides several patches, first just moves a function to co-locate the two functions related to configuring RSS via the admin queue, which should help in spotting bugs when comparing the two functions. Fixed an issue where commit e69ff813af35 ("i40e: rework the functions to configure RSS with similar parameters") missed checking whether the seed is NULL before using it and did not use the passed in *lut parameter. Fixed an issue where a previous refactor missed i40e_vsi_config_rss() and the values were being ignored, so checked for the fields and used them instead of default values. Lastly replaced calls to create_singlethread_workqueue() with alloc_workqueue() to provide more control over workqueue creation and allows explicit setting of the desired mode of operation. Mitch adds link speed to log messages and reports speed through ethtool. Carolyn refactors tail bump check and fixes byte ordering problems found when enabling this feature support. Adds support for HMC resources and profile commands for x722 firmware. Heinrich Schuchardt fixes format identifiers from %u to %d since the variable is defined as an integer. Catherine fixes an issue where there was a race condition between the completion of the client open and calls to the client ops, so ensured that client ops are not called until we are sure client is open. Harshitha makes sure that i40e_client_release() does not try to use an adapter pointer which may not be initialized, so make sure it is. Joe Perches fixes the use of the local macro XSTRINGIFY() to use __stringify() instead. Avinash corrects the mutex usage in client_subtask(). Fixed the RDMA client to open again after reset since it is closed during a PF reset. Jeff (me) clean up whitespace issues, where indentation was done inconsistently and with spaces versus tabs. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2016-08-19samples/bpf: Add tunnel set/get tests.William Tu
The patch creates sample code exercising bpf_skb_{set,get}_tunnel_key, and bpf_skb_{set,get}_tunnel_opt for GRE, VXLAN, and GENEVE. A native tunnel device is created in a namespace to interact with a lwtunnel device out of the namespace, with metadata enabled. The bpf_skb_set_* program is attached to tc egress and bpf_skb_get_* is attached to egress qdisc. A ping between two tunnels is used to verify correctness and the result of bpf_skb_get_* printed by bpf_trace_printk. Signed-off-by: William Tu <u9012063@gmail.com> Signed-off-by: David S.

We've already set sk to sock->sk and dereferenced it, so if it's NULL we would have crashed already. Moreover, if it was NULL we would have crashed anyway when jumping to 'out' and trying to unlock the sock. Furthermore, if we had assigned a different value to 'sk' we would have been calling lock_sock() and release_sock() on different sockets.

2016-08-19qed: utilize FW 8.10.10.0Yuval Mintz
This new firmware for the qed* adpaters fixes several issues: - Better blocking of malicious VFs. - After FLR, Tx-switching [internal routing] of packets might be incorrect. - Deletion of unicast MAC filters would sometime have side-effect of corrupting the MAC filters configred for a device. It also contains fixes for future qed* drivers that *hopefully* would be sent for review in the near future. In addition, it would allow driver some new functionality, including: - Allowing PF/VF driver compaitibility with old drivers [running pre-8.10.5.0 firmware]. - Better debug facilities.

Now that we have converted the drivers into a proper platform device driver, we can use the device managed helper functions to simplify the error paths a bit wrt. register resources and IRQs. Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-08-19net: dsa: bcm_sf2: Make it a real platform device driverFlorian Fainelli
The Broadcom Starfighter 2 switch driver should be a proper platform driver, now that the DSA code has been updated to allow that, register a switch device, feed it with the proper configuration data coming from Device Tree and register our switch device with DSA. The bulk of the changes consist in moving what bcm_sf2_sw_setup() did into the platform driver probe function. Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S.

Andrew Lunn says: ==================== Fix mv88e6xxx wait function The mv88e6xxx wait function can be upset of the system has nots of other things to do and a sleep takes a lot longer than expected. Fix this be using a fixed number of iterations, rather than a fixed walkclock time. Witht that change made, it is possible to consoliate another wait function. A wait actually timing out should not happen and when it does, it means something serious is wrong. Make sure an error is logged, since not all callers will log an error. ==================== Reviewed-by: Vivien Didelot <vivien.didelot@savoirfairelinux.com> Signed-off-by: David S.

2016-08-19dsa: mv88e6xxx: Timeout based on iterations, not timeAndrew Lunn
The mv88e6xxx driver times out operations on the switch based on looping until an elapsed wall clock time is reached. However, if usleep_range() sleeps much longer than expected, it could timeout with an error without actually checking to see if the devices has completed the operation. So replace the elapsed time with a fixed upper bound on the number of loops. Testing on various switches has shown that switches takes either 0 or 1 iteration, so a maximum of 16 iterations is a safe limit. Signed-off-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S.

Andrew Lunn says: ==================== PHY Kconfig and Makefile cleanup The Ethernet PHY directory has slowly been getting more entries. Split the entries in the Makefile and Kconfig into MDIO bus drivers and PHYs. Within these two groups, sort them. This should reduce merge conflicts and aid finding what one searches for. The Kconfig text contains redundant "Driver for" and "Support for" which add little value, make the vendor less obvious, and defeat the shortcut key in the menu.

An upcoming feature of IBM VNIC protocol is the ability to configure redundant backing devices for a VNIC client. In case of a failure on the current backing device, the driver will receive a signal from the hypervisor indicating that a failover will occur. The driver will then wait for a message from the backing device before establishing a new connection. Signed-off-by: Thomas Falcon <tlfalcon@linux.vnet.ibm.com> Signed-off-by: David S.
