2017-01-02qed*: Update to dual-licenseMintz, Yuval15-57/+368
Since the submission of the qedr driver, there's inconsistency in the licensing of the various qed/qede files - some are GPLv2 and some are dual-license.

2016-11-30qed*: Handle-based L2-queues.Mintz, Yuval1-27/+29
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.

2016-11-30qed: Optimize qed_chain datapath usageMintz, Yuval1-64/+80
The chain structure and functions are widely used by the qed* modules, both for configuration and datapath. E.g., qede's Tx has one such chain and its Rx has two. Currently, the strucutre's fields which are required for datapath related functions [produce/consume] are intertwined with fields which are required only for configuration purposes [init/destroy/etc.]. This patch re-arranges the chain structure so that all the fields which are required for datapath usage could reside in a single cacheline instead of the two which are required today.

2016-10-31qed: Learn resources from management firmwareTomer Tayar1-1/+1
Currently, each interfaces assumes it receives an equal portion of HW/FW resources, but this is wasteful - different partitions [and specifically, parititions exposing different protocol support] might require different resources. Implement a new resource learning scheme where the information is received directly from the management firmware [which has knowledge of all of the functions and can serve as arbiter].

2016-10-31qed*: Management firmware - notifications and defaultsSudarsana Kalluru1-0/+28
Management firmware is interested in various tidbits about the driver - including the driver state & several configuration related fields [MTU, primtary MAC, etc.]. This adds the necessray logic to update MFW with such configurations, some of which are passed directly via qed while for others APIs are provide so that qede would be able to later configure if needed. This also introduces a new default configuration for MTU which would replace the default inherited by being an ethernet device.

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.

2016-10-14qed*: Allow unicast filteringYuval Mintz1-0/+1
Apparently qede fails to set IFF_UNICAST_FLT, and as a result is not actually performing unicast MAC filtering. While we're at it - relax a hard-coded limitation that limits each interface into using at most 15 unicast MAC addresses before turning promiscuous. Instead utilize the HW resources to their limit.

2016-10-14qed*: Fix Kconfig dependencies with INFINIBAND_QEDRYuval Mintz1-1/+1
The qedr driver would require a tristate Kconfig option [to allow it to compile as a module], and toward that end we've added the INFINIBAND_QEDR option. But as we've made the compilation of the qed/qede infrastructure required for RoCE dependent on the option we'd be facing linking difficulties in case that QED=y or QEDE=y, and INFINIBAND_QEDR=m. To resolve this, we seperate between the INFINIBAND_QEDR option and the infrastructure support in qed/qede by introducing a new QED_RDMA option which would be selected by INFINIBAND_QEDR but would be a boolean instead of a tristate; Following that, the qed/qede is fixed based on this new option so that all config combinations would be supported.

2016-08-23qed*: Add support for VFs over legacy PFsYuval Mintz1-0/+3
Modern VFs can't run on old non-compatible as the fastpath HSI is slightly changed - but as the HSI is actually very close [basically, a single bit whose meaning flipped] this can be supported with small modifications.

It also contains fixes for future qed* drivers that *hopefully* would be sent for review in the near future. In addition, it would allow driver some new functionality, including: - Allowing PF/VF driver compaitibility with old drivers [running pre-8.10.5.0 firmware]. - Better debug facilities.
