Is this meant to be "all other soft error types"? If so, how does it differ from UNKNOWN? (if not, what is it?)

Should this include the switch_id in the callback?

Memory corruption can be classified into two buckets. One is hard failure and the other is soft failure. Soft failure/error is tend to cause by a single event upset (SEU) to the data memory. Hard failure is tend to be the result of raw defects in silicon wafer, natural aging or electrical over stress causing the P/N junction to break down permanently. Soft error is opposite from hard failure, that is, the memory corruption will go away after the device is reset or re- initialized.
This PR introduces a callback for Soft Error and Recovery mechanism and associated recovery type and log information.
