2018-12-01net: aquantia: fix rx checksum offload bitsDmitry Bogdanov1-1/+1
The last set of csum offload fixes had a leak: Checksum enabled status bits from rx descriptor were incorrectly interpreted. Consequently all the other valid logic worked on zero bits. That caused rx checksum offloads never to trigger. Tested by dumping rx descriptors and validating resulting csum_level.

2018-12-01net: stmmac: Move debugfs init/exit to ->probe()/->remove()Thierry Reding1-10/+13
Setting up and tearing down debugfs is current unbalanced, as seen by this error during resume from suspend: [ 752.134067] dwc-eth-dwmac 2490000.ethernet eth0: ERROR failed to create debugfs directory [ 752.134347] dwc-eth-dwmac 2490000.ethernet eth0: stmmac_hw_setup: failed debugFS registration The imbalance happens because the driver creates the debugfs hierarchy when the device is opened and tears it down when the device is closed. There's little gain in that, and it could be argued that it is even surprising because it's not usually done for other devices. Fix the imbalance by moving the debugfs creation and teardown to the driver's ->probe() and ->remove() implementations instead. Note that the ring descriptors cannot be read while the interface is down, so make sure to return an empty file when the descriptors_status debugfs file is read.

2018-11-30net/mlx5: Remove all deprecated software versions of FW eventsSaeed Mahameed1-91/+1
Before the new mlx5 event notification infrastructure and API, mlx5_core used to process all events before forwarding them to mlx5 interfaces (mlx5e/mlx5_ib) and used to translate the event type enum to a software defined enum, this is not needed anymore since it is ok for mlx5e and mlx5_ib to receive FW events as is, at least the few ones mlx5 core allows. mlx5e and mlx5_ib already moved to use the new API and they only handle FW events types, it is now safe to remove all equivalent software defined events and the logic around them. Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>
2018-11-30net/mlx5: Allow forwarding event type general event as isSaeed Mahameed1-0/+1

The mlx5_interface->event callback is not used by mlx5e/mlx5_ib anymore. We totally remove the delayed events logic work around, since with the dynamic notifier registration API it is not needed anymore, mlx5_ib can register its notifier and start receiving events exactly at the moment it is ready to handle them.

2018-11-30net/mlx5: Allow port change event to be forwarded to driver notifiers chainSaeed Mahameed1-0/+16
The idea is to allow mlx5 core interfaces (mlx5e/mlx5_ib) to be able to receive some allowed FW events as is via the new notifier API. In this patch we allow forwarding port change event to mlx5 core interfaces (mlx5e/mlx5_ib) as it was received from FW. Once mlx5e and mlx5_ib start using this event we can safely remove the redundant software version of it and its translation logic. Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>

Use atomic notifier chain to fire events to mlx5 core driver consumers (mlx5e/mlx5_ib) and provide mlx5 register/unregister notifier API. This API will replace the current mlx5_interface->event callback and all the logic around it, especially the delayed events logic introduced by commit 97834eba7c19 ("net/mlx5: Delay events till ib registration ends") Which is not needed anymore with this new API where the mlx5 interface can dynamically register/unregister its notifier.

2018-11-29net: ethernet: ave: Set initial wol state to disabledKunihiko Hayashi1-1/+5
If wol state of phy hardware is enabled after reset, phy_ethtool_get_wol() returns that wol.wolopts is true. However, since net_device.wol_enabled is zero and this doesn't apply wol state until calling ethtool_set_wol(), so mdio_bus_phy_may_suspend() returns true, that is, it's in a state where phy can suspend even though wol state is enabled. In this inconsistency, phy_suspend() returns -EBUSY, and at last, suspend sequence fails with the following message: dpm_run_callback(): mdio_bus_phy_suspend+0x0/0x58 returns -16 PM: Device 65000000.ethernet-ffffffff:01 failed to suspend: error -16 PM: Some devices failed to suspend, or early wake event detected In order to fix the above issue, this patch forces to set initial wol state to disabled as default.
