Let's rephrase the paragraph in the following way:

On SFN8xxx with firmware version before v6.4.2.1007 driver reload is needed
after switching from full-feature to low-latency firmware variant since 
the driver
still thinks that firmware supports encapsulation, but firmware does not
tolerate request to provide info about outer frame in Rx events.
