* qed: Split rdma content between qed_rdma and qed_roceKalderon, Michal2017-06-211-135/+16
| | | | | | | | | | | | | This patch places common iWARP / RoCE code in qed_rdma and roce specific code in qed_roce There is one new function ( qed_roce_setup ) added, the rest of the patch removes content from the files and removes some static definitions.

* qed: SPQ async callback registrationMichal Kalderon2017-06-201-6/+0
| | | | | | | | | | | | | | | 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.

* qed*: LL2 callback operationsMichal Kalderon2017-06-091-43/+0
| | | | | | | | | | | | | | | | | | LL2 today is interrupt driven - when tx/rx completion arrives [or any other indication], qed needs to operate on the connection and pass the information to the protocol-driver [or internal qed consumer]. Since we have several flavors of ll2 employeed by the driver, each handler needs to do an if-else to determine the right functionality to use based on the connection type. In order to make things more scalable [given that we're going to add additional types of ll2 flavors] move the infrastrucutre into using a callback-based approach - the callbacks would be provided as part of the connection's initialization parameters.

* qed: verify RoCE resource bitmaps are releasedRam Amrani2017-05-011-0/+2
| | | | | | | | | Add mechanism to verify RoCE resources are released prior to freeing the bitmaps. If this is not the case, print what resources were not released.

* qed*: Utilize Firmware 8.15.3.0Mintz, Yuval2017-03-131-3/+8
| | | | | | | | | | | | | | | | | | | | | | | | | This patch advances the qed* drivers into using the newer firmware - This solves several firmware bugs, mostly related [but not limited to] various init/deinit issues in various offloaded protocols. It also introduces a major 4-Cached SGE change in firmware, which can be seen in the storage drivers' changes. In addition, this firmware is required for supporting the new QL41xxx series of adapters; While this patch doesn't add the actual support, the firmware contains the necessary initialization & firmware logic to operate such adapters [actual support would be added later on].

* qed*: Update to dual-licenseMintz, Yuval2017-01-011-1/+1
| | | | | | | | | | | 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. Since qedr requires dual-license and it's dependent on both, we're updating the licensing of all qed/qede source files. Signed-off-by: Yuval Mintz <Yuval.Mintz@cavium.com> Signed-off-by: David S.

* qed: Additional work toward cleaning C=1Yuval Mintz2016-10-141-20/+0
| | | | | | | | | | This cleans many of the warnings that would arise in qed as a result of compilations with C=1; Most of those are the addition of missing 'static' to functions, although there are several other fixes as well.

* qed*: Fix Kconfig dependencies with INFINIBAND_QEDRYuval Mintz2016-10-141-28/+47
| | | | | | | | | | | | | | | | | | | | | 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.
