It depends. If the operating system in use has certain optimisations and misses certain others, it helps in some cases, including an important case. But in general, more precise information from the hardware to the OS helps the OS work faster, and "eth0 needs care now" is more precise than "either eth0, eth1, eth2 or a combination needs care now".
