[SCSI] libfc: Declare local functions static

2012-01-16T08:45:48+00:00

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.

[SCSI] libfc: cache align struct fc_fcp_pkt fields

2011-10-02T17:55:07+00:00

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

2011-06-29T21:28:39+00:00

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.

[SCSI] libfc: introduce LLD event callback

2011-02-12T17:09:04+00:00

This patch enables LLD to listen to rport events and perform LLD
specific operations based on the rport event. This patch also stores
sp_features and spp_type in rdata for further reference by LLD.

[SCSI] libfc: export seq_release() for users of seq_assign()

2011-02-12T17:03:40+00:00

Target modules using lport->tt.seq_assign() get a hold on the
exchange but have no way of releasing it.  Add that.

[SCSI] libfc: add hook to notify providers of local port changes

2011-02-12T17:02:20+00:00

When an SCST provider is registered, it needs to know what
local ports are available for configuration as targets.

Add a notifier chain that is invoked when any local port
that is added or deleted.

Maintain a global list of local ports and add an
interator function that calls a given function for
every existing local port.  This is used when first
loading a provider.

[SCSI] libfc: add local port hook for provider session lookup

2011-02-12T17:02:17+00:00

The target provider needs a per-instance lookup table
or other way to lookup sessions quickly without going through
a linear list or serializing too much.

Add a simple void * array indexed by FC-4 type to the fc_lport.

[SCSI] libfc: add method for setting handler for incoming exchange

2011-02-12T17:01:21+00:00

Add a method for setting handler for incoming exchange.
For multi-sequence exchanges, this allows the target driver
to add a response handler for handling subsequent sequences,
and exchange manager resets.

The new function is called fc_seq_set_resp().
