[SCSI] libfcoe: rename libfcoe.c to fcoe_cltr.c for the coming fcoe_transport.c

2011-02-12T17:06:25+00:00

The existing libfcoe.c is mostly for FIP support, rename it to reflect that fact and so we can add fcoe_transport.c to the make file to include both into the libfcoe kernel module.

[SCSI] libfcoe: move logging macros into the local libfcoe.h header file

2011-02-12T17:05:22+00:00

libfcoe kernel module debug macros will used by the fcoe transport code as well when later it gets added. Signed-off-by: Yi Zou Signed-off-by: Robert Love Signed-off-by: James Bottomley

[SCSI] libfcoe: change fip_select to return new FCF

2010-12-21T18:24:34+00:00

Neaten several calls to fip_select() by having it return the pointer to the new FCF. Signed-off-by: Joe Eykholt Signed-off-by: Robert Love Signed-off-by: James Bottomley

[SCSI] libfcoe: reorder FCF list to put latest advertiser first

2010-12-21T18:24:33+00:00

When there are several FCFs to choose from, the one most likely to accept a FLOGI on certian switches is the one that last answered a multicast solicit. So, when receiving an advertisement, move the FCF to the front of the list so that it gets chosen first among those with the same priority. Without this, more FLOGIs need to be sent in a test with multiple FCFs and a switch in NPV mode, but it still eventually finds one that accepts the FLOGI.

[SCSI] libfcoe: add debug message for FCF destination MAC

2010-12-21T18:24:33+00:00

When multiple FCFs to the same fabric exist, the debug messages all look alike. Change the message to include the MAC address. Signed-off-by: Joe Eykholt Signed-off-by: Robert Love Signed-off-by: James Bottomley

[SCSI] libfcoe: retry rejected FLOGI to another FCF if possible

2010-12-21T18:24:32+00:00

Switches using multiple-FCFs may reject FLOGI in order to balance the load between multiple FCFs. Even though the FCF was available, it may have more load at the point we actually send the FLOGI. If the FLOGI fails, select a different FCF if possible, among those with the same priority. If no other FCF is available, just deliver the reject to libfc for retry.

[SCSI] libfcoe: fix checking of conflicting fabrics in fcoe_ctlr_select()

2010-12-21T18:24:32+00:00

The check for conflicting fabrics in fcoe_ctlr_select() ignores any FCFs that aren't usable. This is a minor problem now but becomes more pronounced after later patches. Signed-off-by: Joe Eykholt Signed-off-by: Robert Love Signed-off-by: James Bottomley

[SCSI] libfcoe: move some timer code to make it reusable.

2010-12-21T18:24:29+00:00

Move some of the code in fcoe_ctlr_timer_work() to fcoe_ctlr_select() so that it can be shared with another function in a forthcoming patch. Signed-off-by: Joe Eykholt Signed-off-by: Robert Love Signed-off-by: James Bottomley

[SCSI] libfcoe: update FIP FCF announcements

2010-12-21T18:24:28+00:00

Move the announcement code to a separate function for reuse in a forthcoming patch. For messages regarding FCF timeout and selection, use the previously-announced FCF MAC address (dest_addr) in the fcoe_ctlr struct. Only print (announce) the FCF if it is new. Print MAC for timed-out or deselected FCFs. Signed-off-by: Joe Eykholt Signed-off-by: Robert Love Signed-off-by: James Bottomley
