* [SCSI] bfa: Fix crash when symb name set for offline vportVijaya Mohan Guvva2013-12-033-8/+14
| | | | | | | | | | This patch fixes a crash when tried setting symbolic name for an offline vport through sysfs. Crash is due to uninitialized pointer lport->ns, which gets initialized only on linkup (port online).

| * SCSI: remove unnecessary pci_set_drvdata()Jingoo Han2013-10-141-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | Since commit 0998d0631001288a5974afc0b2a5f568bcdecb4d (device-core: Ensure drvdata = NULL when no driver is bound), the driver core clears the driver data to NULL after device_release or on probe failure. Thus, it is not needed to manually clear the device driver data to NULL.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Root cause: When kernel crashes, On brocade 815/825 adapters, bfa IOC state machine and FW doesn't get a notification and hence are not cleanly shutdown.

In static D-port mode, user configures the port to D-port mode and starts the test, but in dynamic D-port, once the Brocade switch port is configured to D-port, it will reject the regular FLOGI from HBA with reason that it is in D-port mode. So based on the reason code HBA port will turn itself into D-port and start diagnostic test.

| * [SCSI] bfa: fix faulty handling of events in lps smVijay Mohan Guvva2013-06-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a switch disable/enable or a reboot is done, the HBA port gets an offline and a subsequent online notification. When the port comes up a link up notification is sent to bfa from the firmware. The bfa then send an FLOGI to the firmware which is sent out on the wire. The switch port meanwhile goes offline (presumably for diagnostics) which causes the switch not to respond to the FLOGI. The link down notification is sent to the HBA driver. However owing to a bug in the lps state machine handling the lps state machine does not move to sm_init state (it remains in sm_login state and send a login complete message to fcs). This results in a zero PID assignment as the login is not really complete. This fix is to correctly handle the events in lps state machine.

* [SCSI] bfa: Fix few attributes in the RHBA CT passthru commandKrishna Gudipati2012-10-073-10/+11
| | | | | | | | | | | - Made changes to set the RHBA command max payload based on the port configured frame size. - Made changes to fix the driver/fw version size in FMDI structure. - Fix to pass the fw version for FDMI attribute type FDMI_HBA_ATTRIB_FW_VERSION rather than driver version.

* [SCSI] bfa: Add support for FC Arbitrated Loop topology.Krishna Gudipati2012-10-0712-119/+713
| | | | | | | | | | | | | | | | - Add private loop topology support at 2G/4G/8G speeds with following limitations 1. No support for multiple initiators in the loop 2. No public loop support. If attached to a loop with an FL_Port, device continues to work as a private NL_Port in the loop 3. No auto topology detection. User has to manually set the configured topology to loop if attaching to loop. - When loop topology is configured, enabling FC port features QoS/Trunk/TRL are not allowed and vice versa.
