 update 

David, 
sorry for the late response. I agree that with stable versions the driver version is not good indication for which exact code is running.
however, we have many users that port the latest ena driver as-is from kernel sources into their older kernels, mainly to pull new ENA features (e.g. low latency queues). for those cases, the driver version helps us to identify the driver's code, so in practice this just works fine.

Series applied and patch #1 queued up for -stable.

But I want to reiterate what Andrew said, the version is so increibly
useless and stupid.

I'm going to submit the fix to -stable, and then people will then
doubly and triply have no relationship between driver version number
and what fixes exist.
