Re: [PATCH] iwlwifi: mvm: retry init flow if failed

In some very rare cases the init flow may fail.  In many cases, this is
recoverable, so we can retry.  Implement a loop to retry two more times
after the first attempt failed.

This can happen in two different situations, namely during probe and
during mac80211 start.  For the first case, a simple loop is enough.
For the second case, we need to add a flag to prevent mac80211 from
trying to restart it as well, leaving full control with the driver.

Hi Kalle,

Can you take this to v5.16?

It fixes a rare but critical issue that causes the NIC to become
unusable until the next reboot...

I'll assign it to you in patchwork.

Thanks!
