From: Muneendra <muneendra.kumar@xxxxxxxxxxxx> The LLDD and the stack currently process FPINs received from the fabric, but the stack is not aware of any action taken by the driver to alleviate congestion. The current interface between the driver and the SCSI stack is limited to passing the notification mainly for statistics and heuristics. The reaction to an FPIN could be handled either by the driver or by the stack (marginal path and failover). This patch enhances the interface to indicate if action on an FPIN has already been reacted to by the LLDDs or not.Add an additional flag to fc_host_fpin_rcv() to indicate if the FPIN has been acknowledged/reacted to by the driver. Also added a new event code FCH_EVT_LINK_FPIN_ACK to notify to the user that the event has been acknowledged/reacted by the LLDD driver Signed-off-by: Anil Gurumurthy <agurumurthy@xxxxxxxxxxx> Signed-off-by: Nilesh Javali <njavali@xxxxxxxxxxx> Signed-off-by: Muneendra <muneendra.kumar@xxxxxxxxxxxx> --- drivers/scsi/lpfc/lpfc_els.c | 2 +- drivers/scsi/qla2xxx/qla_isr.c | 2 +- drivers/scsi/scsi_transport_fc.c | 10 +++++++--- include/scsi/scsi_transport_fc.h | 4 +++- 4 files changed, 12 insertions(+), 6 deletions(-)
