2016-04-20fm10k: Add support for bulk Tx cleanup & cleanup boolean logicAlexander Duyck
This patch enables bulk free in Tx cleanup for fm10k and cleans up the boolean logic in the polling routines for fm10k in the hopes of avoiding any mix-ups similar to what occurred with i40e and i40evf.

2016-04-20fm10k: remove debug-statistics supportJacob Keller
This change fixes an (ab)use of the ethtool stats API, which could result in corrupt memory or misleading stat output. The ethtool stats API is not robust enough to handle varying number of statistics due to how it requests the size and allocates memory. Remove the poorly conceived support originally added for extra debug statistics. In the future, a new stats API may open up the ability to display these statistics.

2016-04-20fm10k: add helper functions to set strings and data for ethtool statsJacob Keller
Reduce duplicate code and the amount of indentation by adding fm10k_add_stat_strings and fm10k_add_ethtool_stats functions which help add fm10k_stat structures to the ethtool stats callbacks. This helps increase ease of use for future stat additions, and increases code readability.

2016-04-19arcnet: com90xx: add __init attributeJulia Lawall
Add __init attribute on a function that is only called from other __init functions and that is not inlined, at least with gcc version 4.8.4 on an x86 machine with allyesconfig. Currently, the function is put in the .text.unlikely segment. Declaring it as __init will cause it to be put in the .init.text and to disappear after initialization. The result of objdump -x on the function before the change is as follows: 0000000000000000 l F .text.unlikely 00000000000000bf check_mirror And after the change it is as follows: 0000000000000000 l F .init.text 00000000000000ba check_mirror Done with the help of Coccinelle. The semantic patch checks for local static non-init functions that are called from an __init function and are not called from any other function.

2016-04-18hv_netvsc: Implement support for VF drivers on Hyper-VKY Srinivasan
Support VF drivers on Hyper-V. On Hyper-V, each VF instance presented to the guest has an associated synthetic interface that shares the MAC address with the VF instance. Typically these are bonded together to support live migration. By default, the host delivers all the incoming packets on the synthetic interface. Once the VF is up, we need to explicitly switch the data path on the host to divert traffic onto the VF interface. Even after switching the data path, broadcast and multicast packets are always delivered on the synthetic interface and these will have to be injected back onto the VF interface (if VF is up). This patch implements the necessary support in netvsc to support Linux VF drivers. Signed-off-by: K. Y.

2016-04-16nfp: add async reconfiguration mechanismJakub Kicinski
Some callers of nfp_net_reconfig() are in atomic context so we used to busy wait for commands to complete. In worst case scenario that means locking up a core for up to 5 seconds when a command times out. Lets add a timer-based mechanism of asynchronously checking whether reconfiguration completed successfully for atomic callers to use. Non-atomic callers can now just sleep. The approach taken is quite simple because (1) synchronous reconfigurations always happen under RTNL (or before device is registered); (2) we can coalesce pending reconfigs. There is no need for request queues, timer which eventually takes a look at reconfiguration result to report errors is good enough.

This patch updates the IP tunnel core function iptunnel_handle_offloads so that we return an int and do not free the skb inside the function. This actually allows us to clean up several paths in several tunnels so that we can free the skb at one point in the path without having to have a secondary path if we are supporting tunnel offloads. In addition it should resolve some double-free issues I have found in the tunnels paths as I believe it is possible for us to end up triggering such an event in the case of fou or gue.

Due to the fact that the udp socket is destructed asynchronously in a work queue, we have some nondeterministic behavior during shutdown of vxlan tunnels and creating new ones. Fix this by keeping the destruction process synchronous in regards to the user space process so IFF_UP can be reliably set. udp_tunnel_sock_release destroys vs->sock->sk if reference counter indicates so. We expect to have the same lifetime of vxlan_sock and vxlan_sock->sock->sk even in fast paths with only rcu locks held. So only destruct the whole socket after we can be sure it cannot be found by searching vxlan_net->sock_list.
