2016-05-04drivers: replace dev->trans_start accesses with dev_trans_startFlorian Westphal10-10/+10
a trans_start struct member exists twice: - in struct net_device (legacy) - in struct netdev_queue Instead of open-coding dev->trans_start usage to obtain the current trans_start value, use dev_trans_start() instead. This is not exactly the same, as dev_trans_start also considers the trans_start values of the netdev queues owned by the device and provides the most recent one. For legacy devices this doesn't matter as dev_trans_start can cope with netdev trans_start values of 0 (they are ignored). This is a prerequisite to eventual removal of dev->trans_start.

- Add support to configure trusted vf attribute through trust_vf_ndo. - Upon VF trust setting change we update vport context to refresh allmulti/promisc or any trusted vf attributes that we didn't trust the VF for before. - Lock the eswitch state lock on vport event in order to synchronise the vport context updates , this will prevent contention with vport trust setting change which will trigger vport mac list update.

2016-05-04net/mlx5: E-Switch, Implement promiscuous rx modes vf request handlingMohamad Haj Yahia2-6/+267
Add promisc_change as a trigger to vport context change event. Add set vport promisc/allmulti functions to add vport to promiscuous flowtable rules. Upon promisc/allmulti rx mode vf request add the vport to the relevant promiscuous group (Allmulti/Promisc group) so the relevant traffic will be forwarded to it. Upon allmulti vf request add the vport to each existing multicast fdb rule. Upon adding/removing mcast address from a vport, update all other allmulti vports.

Configure ingress and egress vport ACL rules according to spoofchk admin parameters. Ingress ACL flow table rules: if (!spoofchk && !vst) allow all traffic. else : 1) one of the following rules : * if (spoofchk && vst) allow only untagged traffic with smac=original mac sent from the VF. * if (spoofchk && !vst) allow only traffic with smac=original mac sent from the VF. * if (!spoofchk && vst) allow only untagged traffic. 2) drop all traffic that didn't hit #1.

2016-05-04bnxt: Add support for segmentation of tunnels with outer checksumsAlexander Duyck1-2/+7
This patch assumes that the bnxt hardware will ignore existing IPv4/v6 header fields for length and checksum as well as the length and checksum fields for outer UDP and GRE headers. I have been told by Michael Chan that this is working. Though this might be somewhat redundant for IPv6 as they are forcing the checksum to be computed for all IPv6 frames that are offloaded. A follow-up patch may be necessary in order to fix this as it is essentially mangling the outer IPv6 headers to add a checksum where none was requested.

2016-05-04net/mlx5e: Fix IPv6 tunnel checksum offloadAlexander Duyck1-2/+1
The mlx5 driver exposes support for TSO6 but not IPv6 csum for hardware encapsulated tunnels. This leads to issues as it triggers warnings in skb_checksum_help as it ends up being called as we report supporting the segmentation but not the checksumming for IPv6 frames. This patch corrects that and drops 2 features that don't actually need to be supported in hw_enc_features since they are Rx features and don't actually impact anything by being present in hw_enc_features.

2016-05-04net/mlx4_en: Add support for inner IPv6 checksum offloads and TSOAlexander Duyck2-7/+33
>From what I can tell the ConnectX-3 will support an inner IPv6 checksum and segmentation offload, however it cannot support outer IPv6 headers. This assumption is based on the fact that I could see the checksum being offloaded for inner header on IPv4 tunnels, but not on IPv6 tunnels. For this reason I am adding the feature to the hw_enc_features and adding an extra check to the features_check call that will disable GSO and checksum offload in the case that the encapsulated frame has an outer IP version of that is not 4. The check in mlx4_en_features_check could be removed if at some point in the future a fix is found that allows the hardware to offload segmentation/checksum on tunnels with an outer IPv6 header.

2016-05-03net: macb: Probe MDIO bus before registering netdevFlorian Fainelli1-12/+19
The current sequence makes us register for a network device prior to registering and probing the MDIO bus which could lead to some unwanted consequences, like a thread of execution calling into ndo_open before register_netdev() returns, while the MDIO bus is not ready yet. Rework the sequence to register for the MDIO bus, and therefore attach to a PHY prior to calling register_netdev(), which implies reworking the error path a bit.

2016-05-03net/mlx5: Unmap only the relevant IO memory mappingGal Pressman1-2/+4
When freeing UAR the driver tries to unmap uar->map and uar->bf_map which are mutually exclusive thus always unmapping a NULL pointer. Make sure we only call iounmap() once, for the actual mapping.
