libfc, fcoe, bnx2fc: Always use fcoe_disc_init for discovery layer initialization

2013-03-25T23:01:10Z

Currently libfcoe is doing some libfc discovery layer initialization outside of libfc. This patch moves this code into libfc and sets up a split in discovery (one time) initialization code and (re-configurable) settings that will come in the next patch.

[SCSI] libfc, fcoe, bnx2fc: cleanup fcoe_dev_stats

2012-07-20T07:31:47Z

The libfc is used by fcoe but fcoe agnostic, and therefore should not have any fcoe references. So renaming fcoe_dev_stats from libfc as its for fc_stats. After that libfc is fcoe string free except some strings for Open-FCoE.org.

[SCSI] libfc: Add support for FDMI

2012-02-19T14:08:58Z

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] libfc: Declare local functions static

2012-01-16T08:45:48Z

Avoid that sparse complains about missing declarations for local functions by declaring these static or by adding an #include directive. Add the __percpu annotation where it is missing. Signed-off-by: Bart Van Assche Reviewed-by: Yi Zou Signed-off-by: Robert Love Signed-off-by: James Bottomley

[SCSI] libfc: cache align struct fc_fcp_pkt fields

2011-10-02T17:55:07Z

Re-arrange its fields to avoid padding and have better cacheline alignments. Removed not used start_time, end_time and last_pkt_time fields. This all reduced this struct size to 448 from 480 and that also reduced one cacheline on x86_64 beside eliminating 8 pads. However kept logical fields together.

[SCSI] libfc, tcm_fc: add ddp_targ() to libfc function template to supprot FCoE DDP in target mode

2011-06-29T21:28:39Z

The fcoe driver can implement ddp_targ() similarly to ddp_setup() when fcoe stack works with existing target frame, e.g., tcm, where the ddp_targ() would eventually point to the underlying hardware driver's implementation of ndo_fcoe_ddp_targ() through net_device_ops. This new API sets up DDP context for target appropriately by setting required bits for DDP context.
