* qed*: Reduce the memory footprint for Rx pathSudarsana Reddy Kalluru2016-10-22
| | | | | | | | | | | | | With the current default values for Rx path i.e., 8 queues of 8Kb entries each with 4Kb size, interface will consume 256Mb for Rx. The default values causing the driver probe to fail when the system memory is low. Based on the perforamnce results, rx-ring count value of 1Kb gives the comparable performance with Rx coalesce timeout of 12 seconds. Updating the default values.

* qede: Add qedr frameworkRam Amrani2016-10-03
| | | | | | | | | | | Adds a skeletal implementation of the qede RoCE driver - The qedr has some dependencies of the state of the underlying base interface. This adds some logic required with mutual registrations and the ability to pass updates on 'intresting' events.

* qed: add support for dcbx.Sudarsana Reddy Kalluru2016-05-17
| | | | | | | | | | | | | 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.

* qed*: Tx-switching configurationYuval Mintz2016-05-12

* qed: Introduce VFsYuval Mintz2016-05-12
| | | | | | | | | | | | | | | | | 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.

* qed*: Conditions for changing linkYuval Mintz2016-04-25
| | | | | | | | | | | | | | | | | There's some inconsistency in current logic determining whether the link settings of a given interface can be changed; I.e., in all modes other than the so-called `deault' mode the interfaces are forbidden from changing the configuration - but even this rule is not applied to all user APIs that may change the configuration. Instead, let the core-module [qed] decide whether an interface can change the configuration by supporting a new API function. We also revise the current rule, allowing all interfaces to change their configurations while laying the infrastructure for future modes where an interface would be blocked from making such a configuration.

* qed: Add module with basic common supportYuval Mintz2015-10-27
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.
