2017-06-02qed: Add support for changing iSCSI macMintz, Yuval
Enhance API between qedi and qed, allowing qedi to inform device's firmware when the iSCSI mac is to be changed. Signed-off-by: Yuval Mintz <Yuval.Mintz@cavium.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-06-01qed: Hold a single array for SBsMintz, Yuval
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, Yuval
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 Tayar
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, Yuval
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.

2017-04-06qed: Provide iSCSI statistics to managementMintz, Yuval
Management firmware can query for some basic iSCSI-related statistics. Provide those just as we do for other protocols. Signed-off-by: Yuval Mintz <Yuval.Mintz@cavium.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-04-06qed: Inform qedi the number of possible CQsMintz, Yuval
Now that management firmware is capable of telling us the number of CQs available for a given PF, qed needs to communicate the number to qedi so it would know have many to use. Signed-off-by: Yuval Mintz <Yuval.Mintz@cavium.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-04-06qed: Add missing stat for new islesMintz, Yuval
Firmware provides a statistic for the number of out-of-order isles it used - fill it in the iscsi-related statistics. Signed-off-by: Yuval Mintz <Yuval.Mintz@cavium.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-04-03qed: Revise QM cofigurationAriel Elior
Refactor and clean up the queue manager initialization logic. Also, this adds support for RoC low latency queues, which later would be used for improving RoCE latency in high throughput scenarios.

2017-03-28qed: Use BDQ resource for storage protocolsMintz, Yuval
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.

2017-01-01qed*: Update to dual-licenseMintz, Yuval
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.
