I found this quote in the newsgroup while I was reading up on ethernet
bonding:

"Most of the servers I am familar with two ethernet ports are designed
to have one used as a backup, as they are both connected to the same
bus. None of them had sufficent bus bandwith to actually drive two
gigabit ethernets anywhere near full capacity. Indeed, depending on
what else was on the bus the performance may be less than one gigabit
interface. " (Frank Stutzman )

What's the way to check if my twin NICs are on the same / different busses?
