      Fix implicit logo and RSCN handling for NVMET · 1c5b12f7
      由 James Smart 提交于 
      NVMET didn't have any RSCN handling at all and
would not execute implicit LOGO when receiving a PLOGI
from an rport that NVMET had in state UNMAPPED.

Clean up the logic in lpfc_nlp_state_cleanup for
initiators (FCP and NVME). NVMET should not respond to
RSCN including allocating new ndlps so this code was
conditionalized when nvmet_support is true.  The check
for NLP_RCV_PLOGI in lpfc_setup_disc_node was moved
below the check for nvmet_support to allow the NVMET
to recover initiator nodes correctly.  The implicit
logo was introduced with lpfc_rcv_plogi when NVMET gets
a PLOGI on an ndlp in UNMAPPED state.  The RSCN handling
was modified to not respond to an RSCN in NVMET.  Instead
NVMET sends a GID_FT and determines if an NVMEP_INITIATOR
it has is UNMAPPED but no longer in the zone membership.

      Add Fabric assigned WWN support. · aeb3c817
      由 James Smart 提交于 
      Adding support for Fabric assigned WWPN and WWNN.

Firmware sends first FLOGI to fabric with vendor version changes.
On link up driver gets updated service parameter with FAWWN assigned port
name.  Driver sends 2nd FLOGI with updated fawwpn and modifies the
vport->fc_portname in driver.

Note:
Soft wwpn will not be allowed when fawwpn is enabled.

      Fix crash after issuing lip reset · 9d3d340d
      由 James Smart 提交于 
      When RPI is not available, driver sends WQE with invalid RPI value and
rejected by HBA.
lpfc 0000:82:00.3: 1:3154 BLS ABORT RSP failed, data:  x3/xa0320008
and
lpfc :2753 PLOGI failure DID:FFFFFA Status:x3/xa0240008

In this case, driver accesses rpi_ids array out of bounds.

Fix:
Check return value of lpfc_sli4_alloc_rpi(). Do not allocate
lpfc_nodelist entry if RPI is not available.

When RPI is not available, we will get discovery timeouts and
command drops for some of the vports as seen below.

lpfc :0273 Unexpected discovery timeout, vport State x0
lpfc :0230 Unexpected timeout, hba link state x5
lpfc :0111 Dropping received ELS cmd Data: x0 xc90c55 x0

      Fix PRLI ACC rsp for NVME · c07f10cd

      PRLI ACC from target is FCP oriented.

Word 0 was wrong. This was noticed by another nvmet-fc vendor that
was testing the lpfc nvme-fc initiator with their target.

Verified results with analyzer.

      locking/atomic, kref: Add kref_read() · 2c935bc5
      由 Peter Zijlstra 提交于 
      Since we need to change the implementation, stop exposing internals.

Provide kref_read() to read the current reference count; typically
used for debug messages.

Kills two anti-patterns:

	atomic_read(&kref->refcount)
	kref->refcount.counter

In fact, these functions are only used in the file in which they are
declared and don't need a declaration, but can be made static.  So this
patch marks these functions with 'static'.
