I believe he's refering to the situation where the soekris is doing the
bridging, since the soekris only has 4 ethernet ports and two pci slots
max it's likely that if you need greater than quantity 3 plus wireless
internal interfaces that you'll need a switch. given the performance
limits of even a 5501 I tend to disagree that the switching traffic
internally in software bridge at less than line rate at 100Mb/s is a
great trade-off vs say using a cheapo gig-e switch.
