[net-next,0/5] ionic: add FLR support

Message

Nelson, Shannon July 12, 2023, 12:20 a.m. UTC

Add support for handing and recovering from a PCI FLR event.
This patchset first moves some code around to make it usable
in multiple paths, then adds the PCI error handler callbacks
for reset_prepare and reset_done.

Example test:
    echo 1 > /sys/bus/pci/devices/0000:2a:00.0/reset

Note: The first patch is cherry-picked from commit 3a7af34fb6e
      because it hasn't made it into net-next as of today and
      the remaining patches depend on this change.  This patch
      can be dropped from this series once net-next is updated.

  ionic: remove dead device fail path
  ionic: extract common bits from ionic_remove
  ionic: extract common bits from ionic_probe
  ionic: pull out common bits from fw_up
