2018-01-02qed*: Utilize FW 8.33.1.0Tomer Tayar
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.

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>
2017-04-06qed: 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>
2017-01-01qed*: 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. Miller <davem@davemloft.net>
2016-12-02qed: Add support for hardware offloaded iSCSI.Yuval Mintz
This adds the backbone required for the various HW initalizations which are necessary for the iSCSI driver (qedi) for QLogic FastLinQ 4xxxx line of adapters - FW notification, resource initializations, etc. Signed-off-by: Arun Easi <arun.easi@cavium.com> Signed-off-by: Yuval Mintz <yuval.mintz@cavium.com> Reviewed-by: Johannes Thumshirn <jthumshirn@suse.de> Reviewed-by: Hannes Reinecke <hare@suse.de> Signed-off-by: David S.
