Subject: [PATCH v7 net-next 00/10] qed: introduce devlink health support

This is a followup implementation after series

https://patchwork.ozlabs.org/project/netdev/cover/20200514095727.1361-1-irusskikh@marvell.com/

This is an implementation of devlink health infrastructure.

With this we are now able to report HW errors to devlink, and it'll take
its own actions depending on user configuration to capture and store the
dump at the bad moment, and to request the driver to recover the device.

So far we do not differentiate global device failures or specific PCI
function failures. This means that some errors specific to one physical
function will affect an entire device. This is not yet fully designed
and verified, will followup in future.

Solution was verified with artificial HW errors generated, existing
tools for dump analysis could be used.

v7: comments from Jesse and Jakub
 - p2: extra edev check
 - p9: removed extra indents
v6: patch 4: changing serial to board.serial and fw to fw.app
v5: improved patch 4 description
v4:
 - commit message and other fixes after Jiri's comments
 - removed one patch (will send to net)
v3: fix uninit var usage in patch 11
v2: fix #include issue from kbuild test robot.

Igor Russkikh (10):
  qed: move out devlink logic into a new file
  qed/qede: make devlink survive recovery
  qed: fix kconfig help entries
  qed: implement devlink info request
  qed: health reporter init deinit seq
  qed: use devlink logic to report errors
  qed*: make use of devlink recovery infrastructure
  qed: implement devlink dump
  qed: align adjacent indent
  qede: make driver reliable on unload after failures
