2016-08-02qed: Fix error return code in qed_resc_alloc()Wei Yongjun1-0/+1
Fix to return error code -EINVAL instead of 0 when EQ elements is too larger, as done elsewhere in this function. Signed-off-by: Wei Yongjun <weiyj.lk@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2016-07-31qed: Correct min bandwidth for 100gYuval Mintz1-1/+1
Driver uses reverse logic when checking if minimum bandwidth configuration applied, causing it to configure the guarantee only on the first hw-function.

2016-06-23qed: Add support for coalescing config read/update.Sudarsana Reddy Kalluru1-0/+104
This patch adds support for configuring the device tx/rx coalescing timeout values in the order of micro seconds. It also adds APIs for upper layer drivers for reading/updating the coalescing values.

2016-06-04qed: Initialize hardware for new protocolsYuval Mintz1-25/+129
RoCE and iSCSI would require some added/changed hw configuration in order to properly run; The biggest single change being the requirement of allocating and mapping host memory for several HW blocks that aren't being used by qede [SRC, QM, TM, etc.]. In addition, whereas qede is only using context memory for HW blocks, the new protocol would also require task memories to be added.

2016-06-04qed: Add iscsi/rdma personalitiesYuval Mintz1-0/+6

2016-06-04qed: Revisit chain implementationYuval Mintz1-60/+254
RoCE driver is going to need a 32-bit chain [current chain implementation for qed* currently supports only 16-bit producer/consumer chains]. This patch adds said support, as well as doing other slight tweaks and modifications to qed's chain API. Signed-off-by: Yuval Mintz <Yuval.Mintz@qlogic.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-06-03qed: Utilize FW 8.10.3.0Yuval Mintz1-13/+55
The New QED firmware contains several fixes, including: - Wrong classification of packets in 4-port devices. - Anti-spoof interoperability with encapsulated packets. - Tx-switching of encapsulated packets. It also slightly improves Tx performance of the device. In addition, this firmware contains the necessary logic for supporting iscsi & rdma, for which we plan on pushing protocol drivers in the imminent future.

2016-05-26qed: Don't config min BW on 100g on link flapYuval Mintz1-0/+7
Currently 100g devices don't support minimum/maximum BW configurations, yet link flaps might cause the driver to attempt to do such a configuration. Prevent this just as we do for the maximum BW.

2016-05-26qed: Add missing 100g init modeYuval Mintz1-0/+7
Some of the HW configurations are currently missing for 100g devices. This can cause various classification issues, as well as prevent device from fully reaching line-rate. Signed-off-by: Yuval Mintz <Yuval.Mintz@qlogic.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2016-05-26qed: Fix allocation in interrupt contextSudarsana Reddy Kalluru1-11/+16
Commit 39651abd2814 ("qed: add support for dcbx") is re-configuring the QM hw-block as part of its sequence. This is done in attention handling context which is non-sleepable, yet memory is allocated in this flow using GFP_KERNEL.

2016-05-17qed: add support for dcbx.Sudarsana Reddy Kalluru1-5/+100
This patch adds the necessary driver support for Management Firmware to configure the device/firmware with the dcbx results. Management Firmware is responsible for communicating the DCBX and driving the negotiation, but the driver has responsibility of receiving async notification and configuring the results in hw/fw. This patch also adds the dcbx support for future protocols (e.g., FCoE) as preparation to their imminent submission.

2016-05-12qed*: Tx-switching configurationYuval Mintz1-1/+2
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 link controlYuval Mintz1-0/+76
This adds support in 2 ndo that allow PF to tweak the VF's view of the link - `ndo_set_vf_link_state' to allow it a view independent of the PF's, and `ndo_set_vf_rate' which would allow the PF to limit the VF speed.

2016-05-12qed*: Support PVID configurationYuval Mintz1-1/+8
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: IOV l2 functionalityYuval Mintz1-1/+9
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.

2016-05-12qed: IOV configure and FLRYuval Mintz1-6/+11
While previous patches have already added the necessary logic to probe VFs as well as enabling them in the HW, this patch adds the ability to support VF FLR & SRIOV disable. It then wraps both flows together into the first IOV callback to be provided to the protocol driver - `configure'. This would later to be used to enable and disable SRIOV in the adapter.

2016-05-12qed: Introduce VFsYuval Mintz1-32/+150
This adds the qed VFs for the first time - The vfs are limited functions, with a very different PCI bar structure [when compared with PFs] to better impose the related security demands associated with them. This patch includes the logic neccesary to allow VFs to successfully probe [without actually adding the ability to enable iov]. This includes diverging all the flows that would occur as part of the pci probe of the driver, preventing VF from accessing registers/memories it can't and instead utilize the VF->PF channel to query the PF for needed information.

2016-05-12qed: Add CONFIG_QED_SRIOVYuval Mintz1-0/+19
Add support for a new Kconfig option for qed* driver which would allow [eventually] the support in VFs. This patch adds the necessary logic in the PF to learn about the possible VFs it will have to support [Based on PCI configuration space and HW], and prepare a database with an entry per-VF as infrastructure for future interaction with said VFs.

2016-04-26qed: Add vport WFQ configuration APIsManish Chopra1-4/+184

2016-03-02qed: Fix error flow on slowpath startYuval Mintz1-40/+49
In case of problems when initializing the chip, the error flows aren't being properly done. Specifically, it's possible that the chip would be left in a configuration allowing it [internally] to access the host memory, causing fatal problems in the device that would require power cycle to overcome.

2016-03-02qed: Support B0 instead of A0Yuval Mintz1-18/+23
BB_A0 is a development model that is will not reach actual clients. In fact, future firmware would simply fail to initialize such chip. This changes the configuration into B0 instead of A0, and adds a safeguard against the slim chance someone would actually try this with an A0 adapter in which case probe would gracefully fail.

Physical link is handled by the management Firmware. This patch lays the infrastructure for attention handling in the driver, as link change notifications arrive via async. attentions, as well the handling of such notifications.

This patch adds a public API for a network driver to work on top of QED.

2015-10-28qed: Add module with basic common supportYuval Mintz1-0/+1277
The Qlogic Everest Driver is the backend module for the QL4xxx ethernet products by Qlogic. This module serves two main purposes: 1. It's responsible to contain all the common code that will be shared between the various drivers that would be used with said line of products. Flows such as chip initialization and de-initialization fall under this category. 2. It would abstract the protocol-specific HW & FW components, allowing the protocol drivers to have a clean APIs which is detached in its slowpath configuration from the actual HSI. This adds a very basic module without any protocol-specific bits. I.e., this adds a basic implementation that almost entirely falls under the first category.
