| * [SCSI] libfc: Add support for FDMINeerav Parikh2012-02-191-0/+213
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for Fabric Device Management Interface as per FC-GS-4 spec. in libfc. Any driver making use of libfc can enable fdmi state machine for a given lport. If lport has enabled FDMI support the lport state machine will transition into FDMI after completing the DNS states and before entering the SCR state. The FDMI state transition is such that if there is an error, it won't stop the lport state machine from transitioning and the it will behave as if there was no FDMI support. The FDMI HBA attributes are registed with the Management server via Register HBA (RHBA) command and the port attributes are reigstered using the Register Port(RPA) command.

* [SCSI] libfcoe: add protocol description of FIP VN2VN modeJoe Eykholt2010-07-282-3/+50
| | | | | | | | | | | | | | | | | | The FC-BB-6 committee is proposing a new FIP usage model called VN_port to VN_port mode. It allows VN_ports to discover each other over a loss-free L2 Ethernet without any FCF or Fibre-channel fabric services. This is point-to-multipoint. There is also a variant of this called point-to-point which provides for making sure there is just one pair of ports operating over the Ethernet fabric. This patch defines the new message type and subtypes as well as one new descriptor type used by VN2VN mode. These are all still at the proposed stage and subject to change.

* [SCSI] libfc: add FLOGI state to rport for VN2VNJoe Eykholt2010-07-281-0/+2
| | | | | | | | | | | | | | | | | | | The FIP proposal for VN_port to VN_port point-to-multipoint operation requires a FLOGI be sent to each remote port. The FLOGI is sent with the assigned S_ID and D_IDs of the local and remote ports. This and the response get FIP-encapsulated for Ethernet. Add FLOGI state to the remote port state machine. This will be skipped if not in point-to-multipoint mode. To reduce a little duplication between PLOGI and FLOGI response handling, added fc_rport_login_complete(), which handles the parameters for the rdata struct.

| | | | | | | | | | | | | | | Resubmitting after incorporating Joe's review comment. Unsolicited PRLO request is now handled by sending LS_ACC, and then relogin to the remote port if an N-port login session exists for that remote port. Note that this patch should be applied on top of Joe Eykholt's "Fix remote port restart problem" patch.

* [SCSI] libfc: register FC4 features with the FC switchJoe Eykholt2009-12-042-1/+18
| | | | | | | | | | | | | | | | | | Customers and certification tests have pointed out that we don't show up on the switch management software as an initiator. On some MDS switches 'show fcns database' command shows libfc initiators as 'fcp' not 'fcp:init' like other initiators. On others switches, I think the switch gets the features by doing a PRLI, but it may be only certain models or under certain configurations. Fix this by registering our FC4 features with the RFF_ID CT request after local port login and after the RFT_ID.

* [SCSI] libfc: rport retry on LS_RJT from certain ELSChris Leech2009-03-061-0/+5
| | | | | | | | | | | | | | | | | This allows any rport ELS to retry on LS_RJT. The rport error handling would only retry on resource allocation failures and exchange timeouts. I have a target that will occasionally reject PLOGI when we do a quick LOGO/PLOGI. When a critical ELS was rejected, libfc would fail silently leaving the rport in a dead state. The retry count and delay are managed by fc_rport_error_retry. If the retry count is exceeded fc_rport_error will be called. When retrying is not the correct course of action, fc_rport_error can be called directly.
