2018-08-14hv/netvsc: Fix NULL dereference at single queue mode fallbackTakashi Iwai
The recent commit 916c5e1413be ("hv/netvsc: fix handling of fallback to single queue mode") tried to fix the fallback behavior to a single queue mode, but it changed the function to return zero incorrectly, while the function should return an object pointer. Eventually this leads to a NULL dereference at the callers that expect non-NULL value. Fix it by returning the proper net_device object.

2018-08-14net: hns3: Fix for phy link issue when using marvell phy driverJian Shen
For marvell phy m88e1510, bit SUPPORTED_FIBRE of phydev->supported is default on. Both phy_resume() and phy_suspend() will check the SUPPORTED_FIBRE bit and write register of fibre page. Currently in hns3 driver, the SUPPORTED_FIBRE bit will be cleared after phy_connect_direct() finished. Because phy_resume() is called in phy_connect_direct(), and phy_suspend() is called when disconnect phy device, so the operation for fibre page register is not symmetrical. It will cause phy link issue when reload hns3 driver. This patch fixes it by disable the SUPPORTED_FIBRE before connecting phy.

2018-08-13net/mlx5e: Ethtool steering, move ethtool callbacksSaeed Mahameed
Move ethool rxnfc callback into en_fs_etthool file where they belong. This will allow us to make many ethtool fs related helper functions static. Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>
2018-08-13net/mlx5e: Ethtool steering, l4 proto supportSaeed Mahameed
Add support for l4 proto ip field in ethtool flow steering. Example: Redirect icmpv6 to rx queue #2 ethtool -U eth0 flow-type ip6 l4proto 58 action 2 Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>
2018-08-13net/mlx5e: Ethtool steering, ip6 supportSaeed Mahameed

Daniel Borkmann says: ==================== pull-request: bpf-next 2018-08-13 The following pull-request contains BPF updates for your *net-next* tree. The main changes are: 1) Add driver XDP support for veth. This can be used in conjunction with redirect of another XDP program e.g. sitting on NIC so the xdp_frame can be forwarded to the peer veth directly without modification, from Toshiaki. 2) Add a new BPF map type REUSEPORT_SOCKARRAY and prog type SK_REUSEPORT in order to provide more control and visibility on where a SO_REUSEPORT sk should be located, and the latter enables to directly select a sk from the bpf map. This also enables map-in-map for application migration use cases, from Martin. 3) Add a new BPF helper bpf_skb_ancestor_cgroup_id() that returns the id of cgroup v2 that is the ancestor of the cgroup associated with the skb at the ancestor_level, from Andrey. 4) Implement BPF fs map pretty-print support based on BTF data for regular hash table and LRU map, from Yonghong. 5) Decouple the ability to attach BTF for a map from the key and value pretty-printer in BPF fs, and enable further support of BTF for maps for percpu and LPM trie, from Daniel. 6) Implement a better BPF sample of using XDP's CPU redirect feature for load balancing SKB processing to remote CPU. The sample implements the same XDP load balancing as Suricata does which is symmetric hash based on IP and L4 protocol, from Jesper. 7) Revert adding NULL pointer check with WARN_ON_ONCE() in __xdp_return()'s critical path as it is ensured that the allocator is present, from Björn. ==================== Signed-off-by: David S.

2018-08-13r8169: don't use MSI-X on RTL8168gHeiner Kallweit
There have been two reports that network doesn't come back on resume from suspend when using MSI-X. Both cases affect the same chip version (RTL8168g - version 40), on different systems. Falling back to MSI fixes the issue. Even though we don't really have a proof yet that the network chip version is to blame, let's disable MSI-X for this version.

Increasing descriptors to 256 from 128 and adjusting the NAPI weight to 64 increases performace on Rx by ~20% on 64byte packets Signed-off-by: Ilias Apalodimas <ilias.apalodimas@linaro.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-08-11net: socionext: Use descriptor info instead of MMIO reads on RxIlias Apalodimas
MMIO reads for remaining packets in queue occur (at least)twice per invocation of netsec_process_rx(). We can use the packet descriptor to identify if it's owned by the hardware and break out, avoiding the more expensive MMIO read operations. This has a ~2% increase on the pps of the Rx path when tested with 64byte packets Signed-off-by: Ilias Apalodimas <ilias.apalodimas@linaro.org> Signed-off-by: David S. Miller <davem@davemloft.net>
