2014-12-09macvlan: allow setting LRO independently of lower deviceMichal Kubeček
Since commit fbe168ba91f7 ("net: generic dev_disable_lro() stacked device handling"), dev_disable_lro() zeroes NETIF_F_LRO feature flag first for a macvlan device and then for its lower device. As an attempt to set NETIF_F_LRO to zero is ignored, dev_disable_lro() issues a warning and taints kernel. Allowing NETIF_F_LRO to be set independently of the lower device consists of three parts: - add the flag to hw_features to allow toggling it - allow setting it to 0 even if lower device has the flag set - add the flag to MACVLAN_FEATURES to restore copying from lower device on macvlan creation Signed-off-by: Michal Kubecek <mkubecek@suse.cz> Signed-off-by: David S.

2014-12-09i40e: let firmware catch the NVM busy errorShannon Nelson
The NVM update operations take time finish asynchronously, and follow-on update requests need to wait for the current one to finish. Early firmware didn't handle this well, so the code had to track the busy state. The released firmware handles the busy state correctly, returning I40E_AQ_RC_EBUSY if an update is still in progress, so the code no longer needs to track this.

In commit 2b4636a5f8ca ("tcp_cubic: make the delay threshold of HyStart less sensitive"), HYSTART_DELAY_MIN was changed to 4 ms. The remaining problem is that using delay_min + (delay_min/16) as the threshold is too sensitive. 6.25 % of variation is too small for rtt above 60 ms, which are not uncommon.

We never negotiate revision > 1, but just to make this code more likely to work when we do, require VERSION_1 with any revision >= 1. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Acked-by: Cornelia Huck <cornelia.huck@de.ibm.com>
2014-12-09virtio_pci: rename virtio_pci -> virtio_pci_commonMichael S. Tsirkin
kbuild does not seem to like it when we name source files same as the module. Let's rename virtio_pci -> virtio_pci_common, and get rid of #include-ing c files. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>

2014-12-09virtio_pci: setup vqs indirectlyMichael S. Tsirkin

2014-12-09virtio_pci: use priv for vq notificationMichael S. Tsirkin
slightly reduce the amount of pointer chasing this needs to do. More importantly, this will easily generalize to virtio 1.0. Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
