[net-next,00/11] 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.

I just realized I was reviewing this old set (somehow my mailer put this
one after the v6 in the message order) #reviewfail

I'll move over to v6 now, sorry for the thrash.
