* [PATCH 2/2] ath10k: fix rssi and rate reporting

RSSI and RATE fields are valid only when START_VALID
bit is set. So, in current implementation we have to
remember/caclulate them when START_VALID and report the same
when only END_VALID is set. In other case during high
RX traffic we will report invalid RSSI (-95) and RATE (6Mbps)
when only END_VALID bit set.

It's not clear for me what (user visible) bug you are fixing, please
describe that in the commit log.

This is the must in case we would like to report rssi + rates correctly.
I describe this in 2/2 - maybe squash them?
Currently during heavy traffic we could have:
> 10 packets with START_VALID - correct RSSI + rates
> 10 packets with END_VALID
> 10 packets with START_VALID - correct RSSI + rates
> 10 packets with END_VALID -
...

Because of that we have to store rssi + rates for case when END_VALID only.
In other case when using monitor we will see:
- 10 packets with correct rssi/rates
- 10 packets with rssi=-95/rate=6Mbps

Nah, better to keep them separated. But in patch 1 please document why
you are doing that, so that I (and others cherry picking ath10k patches)
don't need to guess. For example, you can say "in preparation for foo"
or something like that.

Ok, I understand now. Please document that in patch 2.

And in the future, please double check that your commit logs answer the
question "why?". That will save everyone's time :)
