2016-11-30qed*: Handle-based L2-queues.Mintz, Yuval
The driver needs to maintain several FW/HW-indices for each one of its queues. Currently, that mapping is done by the QED where it uses an rx/tx array of so-called hw-cids, populating them whenever a new queue is opened and clearing them upon destruction of said queues. This maintenance is far from ideal - there's no real reason why QED needs to maintain such a data-structure. It becomes even worse when considering the fact that the PF's queues and its child VFs' queues are all mapped into the same data-structure. As a by-product, the set of parameters an interface needs to supply for queue APIs is non-trivial, and some of the variables in the API structures have different meaning depending on their exact place in the configuration flow. This patch re-organizes the way L2 queues are configured and maintained. In short: - Required parameters for queue init are now well-defined. - Qed would allocate a queue-cid based on parameters. Upon initialization success, it would return a handle to caller. - Queue-handle would be maintained by entity requesting queue-init, not necessarily qed. - All further queue-APIs [update, destroy] would use the opaque handle as reference for the queue instead of various indices. The possible owners of such handles: - PF queues [qede] - complete handles based on provided configuration. - VF queues [qede] - fw-context-less handles, containing only relative information; Only the PF-side would need the absolute indices for configuration, so they're omitted here. - VF queues [qed, PF-side] - complete handles based on VF initialization.

2016-08-22qed: Prevent VFs from pause floodingYuval Mintz
Firmware would silently drop any control frame sent by VF to prevent a malicious VF from generating pause flood in the network. Signed-off-by: Yuval Mintz <Yuval.Mintz@qlogic.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-08-22qed: Add support for legacy VFsYuval Mintz
The 8.10.x FW added support for forward compatability as well as 'future' backward compatibility, but only to those VFs that were using HSI which was 8.10.x based or newer. The latest firmware now supports backward compatibility for the older VFs based on 8.7.x and 8.8.x firmware as well. Signed-off-by: Yuval Mintz <Yuval.Mintz@qlogic.com> Signed-off-by: David S.

2016-08-18qed: Add support for NCSI statistics.Sudarsana Reddy Kalluru
The patch adds driver support for sending the NCSI statistics to the MFW. This is an asynchronous request from MFW. Upon receiving this, driver populates the required data and send it to MFW.

2016-05-12qed*: Tx-switching configurationYuval Mintz
Device should be configured by default to VEB once VFs are active. This changes the configuration of both PFs' and VFs' vports into enabling tx-switching once sriov is enabled. Signed-off-by: Yuval Mintz <Yuval.Mintz@qlogic.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-05-12qed*: IOV support spoof-checkingYuval Mintz
Add support in `ndo_set_vf_spoofchk' for allowing PF control over its VF spoof-checking configuration. Signed-off-by: Yuval Mintz <Yuval.Mintz@qlogic.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-05-12qed*: Support PVID configurationYuval Mintz
This adds support for PF control over the VF vlan configuration. I.e., `ip link ... vf <x> vlan <vid>' should now be supported. 1. <vid> != 0 => VF receives [unknowingly] only traffic tagged by <vid> and tags all outgoing traffic sent by VF with <vid>. 2. <vid> == 0 ==> Remove the pvid configuration, reverting to previous.

2016-05-12qed: Align TLVsYuval Mintz
As the VF infrastructure is supposed to offer backward/forward compatibility, the various types associated with VF<->PF communication should be aligned across all various platforms that support IOV on our family of adapters. This adds a couple of currently missing values, specifically aligning the enum for the various TLVs possible in the communication between them. It then adds the PF implementation for some of those missing VF requests. This support isn't really necessary for the Linux VF as those VFs aren't requiring it [at least today], but are required by VFs running on other OSes. LRO is an example of one such configuration.

2016-05-12qed: IOV l2 functionalityYuval Mintz
This adds sufficient changes to allow VFs l2-configuration flows to work. While the fastpath of the VF and the PF are meant to be exactly the same, the configuration of the VF is done by the PF. This diverges all VF-related configuration flows that originate from a VF, making them pass through the VF->PF channel and adding sufficient logic on the PF side to support them.
