72206323a5 version: 22.11-rc0
Start a new release cycle with empty release notes.

The ABI version becomes 23.0.
The map files are updated to the new ABI major number (23).
The ABI exceptions are dropped and CI ABI checks are disabled because
compatibility is not preserved.
Special handling of removed drivers is also dropped in check-abi.sh and
a note has been added in libabigail.abignore as a reminder.

834d99f388 raw/ntb: add PPD status check for Sapphire Rapids
Add PPD (PCIe Port Definition) status check for SPR (Sapphire Rapids).

Note that NTB on SPR has the same device id with that on ICX, while
the field offsets of PPD Control Register are different. Here, we use
the PCI device revision id to distinguish the HW platform (ICX/SPR)
and check the Port Config Status and Port Definition accordingly.

+---------------------------+--------------------+--------------------+
|          Fields           | Bit Range (on ICX) | Bit Range (on SPR) |
+---------------------------+--------------------+--------------------+
| Port Configuration Status | 12                 | 14                 |
| Port Definition           | 9:8                | 10:8               |

7580f35ea7 raw/ioat: fix build when ioat dmadev enabled
The build of the raw/ioat driver only occurs when the equivalent dmadev
drivers are disabled. Complications occur when the ioat dmadev is being
built but not the idxd. In this case, only the idxd part of raw/ioat
gets built, but the definition of the logtype is in the ioat part,
causing build errors.

  .../raw_ioat_idxd_bus.c.o: In function `idxd_vdev_mmap_wq':
  idxd_bus.c:(.text+0x116): undefined reference to `ioat_pmd_logtype'

Fix this by moving the logtype definition to the common C file, and
renaming it to avoid conflicts with a similarly named value in the
dma/ioat driver.

673c897f4d raw/ifpga: support OFS card probing
PAC N6000 is the first OFS platform, its device id is added to ifpga
device support list.

Previous FPGA platform like Intel PAC N3000 and N5000, FME DFL (Device
Feature List) starts from BAR0 by default, port DFL location is indicated
in PORTn_OFFSET register in FME. In OFS implementation, FME DFL and port
DFL location can be defined individually in PCIe VSEC (Vendor Specific
Extended Capabilities). In this patch, DFL definition is searched in VSEC,
the legacy DFL is used only when DFL VSEC is not present.

In original DFL enumeration process, AFU is expected to locate in port DFL,
but this is not the case in OFS implementation. In this patch, enumeration
can search AFU in any PF/VF which has no FME and port.

2545683564 raw/ifpga: unregister interrupt on close
There is an API rte_pmd_ifpga_cleanup provided by ifpga driver to
free the software resource used by ifpga card. The function call
of rte_pmd_ifpga_cleanup is list below.
rte_pmd_ifpga_cleanup()
  ifpga_rawdev_cleanup()
     rte_rawdev_pmd_release()
       rte_rawdev_close()
         ifpga_rawdev_close()

The interrupts are unregistered in ifpga_rawdev_destroy instead of
ifpga_rawdev_close function, so rte_pmd_ifpga_cleanup cannot free
interrupt resource as expected.

To fix such issue, interrupt unregistration is moved from
ifpga_rawdev_destroy to ifpga_rawdev_close function. The change of
function call of ifpga_rawdev_destroy is as below.
ifpga_rawdev_destroy()
  ifpga_unregister_msix_irq()  // removed
  rte_rawdev_pmd_release()
    rte_rawdev_close()
      ifpga_rawdev_close()

3bc814fc55 raw/ntb: clear all valid doorbell bits on init
Before registering the doorbell interrupt handler callback function,
all the valid doorbell bits within the NTB private data struct should
be cleared to avoid the confusion of the handshake timing sequence
diagram when setting up the NTB connection in back-to-back mode.
