Re: [PATCH v2] octeontx2-af: Fix PF driver crash with kexec kernel booting

Hello:

This patch was applied to netdev/net.git (main)

During a kexec reboot the hardware is not power-cycled, so AF state from
the old kernel can persist into the new kernel. When AF and PF drivers
are built as modules, the PF driver may probe before AF reinitializes
the hardware.

The PF driver treats the RVUM block revision as an indication that AF
initialization is complete. If this value is left uncleared at shutdown,
PF may incorrectly assume AF is ready and access stale hardware state,
leading to a crash.
