2018-01-02qed*: Utilize FW 8.33.1.0Tomer Tayar1-11/+11
Advance the qed* drivers to use firmware 8.33.1.0: Modify core driver (qed) to utilize the new FW and initialize the device with it. This is the lion's share of the patch, and includes changes to FW interface files, device initialization flows, FW interaction flows, and debug collection flows. Modify Ethernet driver (qede) to make use of new FW in fastpath. Modify RoCE/iWARP driver (qedr) to make use of new FW in fastpath. Modify FCoE driver (qedf) to make use of new FW in fastpath. Modify iSCSI driver (qedi) to make use of new FW in fastpath.

2018-01-02qed*: Refactoring and rearranging FW API with no functional impactTomer Tayar1-18/+18
This patch refactors and reorders the FW API files in preparation of upgrading the code to support new FW. - Make use of the BIT macro in appropriate places. - Whitespace changes to align values and code blocks. - Comments are updated (spelling mistakes, removed if not clear). - Group together code blocks which are related or deal with similar matters.

2017-06-20qed: SPQ async callback registrationMichal Kalderon1-1/+23
Whenever firmware indicates that there's an async indication it needs to handle, there's a switch-case where the right functionality is called based on function's personality and information. Before iWARP is added [as yet another client], switch over the SPQ into a callback-registered mechanism, allowing registration of the relevant event-processing logic based on the function's personality. This allows us to tidy the code by removing protocol-specifics from a common file.

2017-06-01qed: Hold a single array for SBsMintz, Yuval1-1/+1
A PF today holds 2 different arrays - one holding information about the HW configuration and one holding information about the SBs that are used by the protocol drivers. These arrays aren't really connected - e.g., protocol driver initializing a given SB would not mark the same SB as occupied in the HW shadow array. Move into a single array [at least for PFs] - hold the mapping of the driver-protocol SBs on the HW entry which they configure.

2017-05-21qed: Correct print in iscsi error-flowMintz, Yuval1-1/+1
If too many CQs are requested, qed would print the available number as if it's a resource and not a feature leading to the wrong print.

2017-05-21qed: Revise alloc/setup/free flowTomer Tayar1-9/+13
Re-organize the logic that allocates and frees memory of various sub-components of the hw-function - a. No need to pass pointers to said structure as parameters; The internal logic knows exactly where to find/set the data. b. Nullify pointers after cleanup to prevent possible errors to re-entrant code.

2017-05-18qed: Utilize FW 8.20.0.0Mintz, Yuval1-3/+0
This pushes qed [and as result, all qed* drivers] into using 8.20.0.0 firmware. The changes are mostly contained in qed with minor changes to qedi due to some HSI changes. Content-wise, the firmware contains fixes to various issues exposed since the release of the previous firmware, including: - Corrects iSCSI fast retransmit when data digest is enabled. - Stop draining packets when receiving several consecutive PFCs. - Prevent possible assertion when consecutively opening/closing many connections. - Prevent possible assertion due to too long BDQ fetch time. In addition, the new firmware would allow us to later add iWARP support in qed and qedr.

2017-04-07qed: Inform qedi the number of possible CQsMintz, Yuval1-0/+11

2017-03-29qed: Use BDQ resource for storage protocolsMintz, Yuval1-11/+21
Until now, qed used some port-defined value as BDQ index for both iSCSI and FCoE. As management firmware now treats BDQ as a resource and tells each PF its BDQ-range, start using a valure from that range instead.
