[SCSI] libfc: Add target reset flag to FCP header file

2009-12-04T18:02:00+00:00

While the target reset task management function has been deprecated in
newer specs, it is still in use by SCSI FC drivers and there is no
real replacement. Add the target reset flag to the FCP header file to
allow usage of this definition in SCSI FC drivers.

[SCSI] libfc: add fcoe_fc_els_lesb to fc_fcoe.h for FC-BB-5 LESB definitions

2009-12-04T18:01:57+00:00

Add struct fcoe_fc_els_lesb as described in FC-BB-5 LESB for FCoE. It has
the same size as LESB defined in FC-FS-3 (struct fc_els_lesb) but members
have different meanings according to FC-BB-5.

[SCSI] libfcoe: add checking disable flag in FIP_FKA_ADV

2009-12-04T18:01:55+00:00

When the D bit is set if the FKA_ADV_Period of the FIP Discovery
Advertisement, the ENode should not transmit period ENode FIP Keep Alive and
VN_Port FIP Keep Alive (FC-BB-5 Rev2, 7.8.3.13).

Note that fcf->flags is taken directly from the fip_header, I am claiming one
bit for the purpose of the FIP_FKA_Period D bit as FIP_FL_FK_ADV_B, and use
FIP_HEADER_FLAGS as bitmask for bits used in fip_header.

[SCSI] libfc: register FC4 features with the FC switch

2009-12-04T18:01:20+00:00

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: Export FC headers

2009-12-04T18:01:05+00:00

Export fc_els.h, fc_fs.h, fc_gs.h and fc_ns.h so that they
may be used by applications.

This will be needed for FC Passthrough applications like fcping,
but could be used by other applications.

Fix to include  to exported files provided by
Chris Leech .

[SCSI] libfc: fix: empty zone causes endless discovery retries.

2009-09-10T17:07:50+00:00

On some switches, an empty zone causes GPN_FT to be rejected
with reason 9 (unable) explanation 7 (FC-4 types not registered),
which causes discovery to be retried endlessly.  Treat this as
just an empty response and consider discovery complete.
