* scsi: qedf: Stop using the SCSI pointerBart Van Assche2022-02-231-1/+9
| | | | | | | | | | | | | Set .cmd_size in the SCSI host template instead of using the SCSI pointer from struct scsi_cmnd. Remove the CMD_SCSI_STATUS() assignment because the assigned value is not used. This patch prepares for removal of the SCSI pointer from struct scsi_cmnd.

* | qed: Remove e4_ and _e4 from FW HSIShai Malin2021-10-041-2/+2
|/ | | | | | | | | | | | | | | | | | | | | | The existing qed/qede/qedr/qedi/qedf code uses chip-specific naming in structures, functions, variables and defines in FW HSI (Hardware Software Interface). The new FW version introduced a generic naming convention in HSI in-which the same code will be used across different versions for simpler maintainability. It also eases in providing support for new features. With this patch every "_e4" or "e4_" prefix or suffix is not needed anymore and it will be removed.

* scsi: qedf: Enable devlink supportJaved Hasan2021-04-131-0/+1
| | | | | | | | | | | | | | | Devlink instance lifetime was linked to qed_dev object. That caused devlink to be recreated on each recovery. Change it by making higher level driver (qede) responsible for lifetime management. This way devlink survives recoveries. qede now stores devlink structure pointer as a part of its device object, devlink private data contains a linkage structure, qed_devlink.

| | | | | | | | | | | | | | | | | | | still probing The MFW may make a call to qed and then to qedf for protocol statistics while the function is still probing. If this happens it's possible that some members of the struct qedf_ctx may not be fully initialized which can result in a NULL pointer dereference or general protection fault. To prevent this, add a new flag call QEDF_PROBING and set it when the __qedf_probe() function is active. Then in the qedf_get_protocol_tlv_data() function we can check if the function is still probing and return immediantely before any uninitialized structures can be touched.

If the qedf_default_prio modparam is set use that 2. If the DCBX FCoE priority is not in range (0..7) use 3 3.

* | scsi: qedf: Corrent VLAN tag insertion in fallback VLAN case.Chad Dupuis2017-08-251-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently in the driver the qedf_ctx attribute vlan_hw_insert is used to which whether to insert a VLAN tag in FIP frames (except for FIP VLAN request which is explicitly sent out untagged at least from the driver's point of view). When we receive a FIP VLAN response, we set qedf->vlan_hw_insert to 0 which makes the qedf_fip_send function insert the VLAN. However when we exhaust our FIP VLAN retries, we do not set qedf->vlan_hw_insert to 0 which means that the driver will not tag the FIP frame with the correct VLAN ID. The result that was observed on the wire is that some entity either in the LL2 or L2 firmware is adding a NULL VLAN tag which can cause FIP solicitation to fail. The offload FCoE frame function, qedf_xmit, does not use the vlan_hw_insert attribute to decide whether to tag frames with the FIP/FCoE VLAN. Instead it unilaterially tags the offload frames with the VLAN ID stored in qedf->vlan_id. This is the correct behavior so the driver can guarantee that non-offload FIP frames go out with the correct VLAN ID. Also use the Linux network layer helpers instead of doing the VLAN insert manually. Also fix setting the fallback VLAN so that it used the module parameter and is not hardcoded to 1002 (though 1002 is the default).

* | scsi: qedf: Use granted MAC from the FCF for the FCoE source address if it ↵Chad Dupuis2017-08-251-1/+0
|/ | | | | | | | | | | | | | | | | | | | | is available. Currently in the driver we've been using the fc_fcoe_set_mac() function to set the source MAC for FCoE traffic. This works well in most cases as it uses the spec. default FCF-MAC. However, if the administrator changes the FCF-MAC switch, then any FCoE traffic we send will be dropped by the switch. Instead we should check the granted MAC from the FLOGI payload and use that address if it is present. Otherwise, fall back to using the the default FCF-MAC and the fabric ID of the port as the FCoE MAC address. Once this address is known we need to set it when doing non-offload traffic, offload traffic and setting the data_src_address libfcoe uses for FIP keep alive messages.

* qed*: Utilize Firmware 8.15.3.0Mintz, Yuval2017-03-131-11/+12
| | | | | | | | | | | | | | | | | | | | | | | | | 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].
