First impression - that's a _lot_ dropped and missed.
Told you.
You did? when your machine is dropping packets, either there is a problem with that machine or your network is overloaded.
"dropped" also includes packets with the wrong MAC address so it could be due to e.g. switch packet flooding (or maybe the switch is actually a hub in disguise). In any case, it counts good packets (without error) received by interface but ignored. So it does not necessarily indicate host, rather overall network configuration issues.
I have no idea what "missed" means.

Well, if it were me, I would investigate - those numbers seem way too high.
That's about 0.1% of all received packets and we do not know for which period. Are those numbers increasing?
