We've got this really bizarre problem, trying to get a bridge/firewall working. My manager and I are almost grasping at straws....

Anyway, I'm using lshw to look at an identical machine, and a Dell 1950 that works when configured as a bridge, and there's one thing I don't know: does anyone know what mingnt is?

MIN_GNT and MAX_LAT

MIN_GNT is used for specifying how long a burst period the device

Devices should specify values that will allow them to most effectively use the PCI bus as well as their internal resources. Values should be chosen assuming that the target does not insert any wait states.
