Subject: [PATCH v4 net-next 0/4] ionic: add FLR support

Add support for handing and recovering from a PCI FLR event.
This patchset first moves some code around to make it usable
from 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

v4:
 - don't remove ionic_dev_teardown() in ionic_probe() in patch 2/4
 - remove clear_bit() change from patch 3/4

v3:
Link: https://lore.kernel.org/netdev/20230717170001.30539-1-shannon.nelson@amd.com/
 - removed first patch, it is already merged into net

v2:
Link: https://lore.kernel.org/netdev/20230713192936.45152-1-shannon.nelson@amd.com/
 - removed redundant pci_save/restore_state() calls

Shannon Nelson (4):
  ionic: extract common bits from ionic_remove
  ionic: extract common bits from ionic_probe
  ionic: pull out common bits from fw_up
  ionic: add FLR recovery support
