In general, you don't need to worry about these, they are just the driver
adjusting itself to the speed of your card/motherboard. You may see a few
of them when the machine is first busy after boot, and then they should
probably stop.

As for your card growing 20-or-so extra ports - I've no idea. Sounds like
confused hardware to me...
