Some network cards have the ability to detect network activity and bascially shut parts of them down until activity is detected. This is a type of power management. In some cases though, I have seen the card not acting fast enough to reactivate the session causing table/index corruption. I believe the cards can be configured not to do this.

This is also a feature of some new PCs with network cards built-in. This can be turned off in the BIOS setup.
