2017-08-24scsi: qedf: Corrent VLAN tag insertion in fallback VLAN case.Chad Dupuis3-16/+15
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).

2017-08-24scsi: qedf: Use granted MAC from the FCF for the FCoE source address if it ↵Chad Dupuis3-26/+51
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.

2017-06-12scsi: qedf: Add bus_reset No-op.Chad Dupuis1-0/+11
We need to add a bus reset no-op as without it some of the LUNs attached to a vport may go offline when the error handler escalates to host reset due to not having a bus reset handler in the driver. What happens is we escalate to host reset which does a soft link down/link up to reset the adapter. However with multiple vports attached it's been observed that if the vports do log back into the target within 5 seconds, the SCSI layer offlines the devices most likely due to a TUR timing out to verify that the device is online. Adding a bus reset handler will cause the TUR to be sent after the bus reset handler where the devices will still be online if the bus reset is initiated by sg_reset (which is the case in the test that was failing). The bus reset will succeed and not needlessly bring the device offline/online. Signed-off-by: Chad Dupuis <chad.dupuis@cavium.com> Signed-off-by: Martin K. Petersen <martin.petersen@oracle.com>

2017-06-12scsi: qedf: Look at all descriptors when processing a clear virtual link.Chad Dupuis1-11/+9
If there are multiple descriptors for a particular type in a clear virtual link we receive, we will not process it correctly but rather take the last value. This can cause us not to not flap the virtual link as the value from the descriptors that we compare against the our stored FCF or fc_lport values may not match. Change this to do a comparison when processing the each descriptor instead of at the end and then set a bool if we need to do the reset.

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].
