The devices below are based on Marvell 98DX8xxx, 98DX4xxx switch chips, or the 98DX3257 model.

1 Depends on the complexity of the routing table. Whole-byte IP prefixes (/8, /16, /24, etc.) occupy less HW space than others (e.g., /22). When the HW route limit is reached, new route entries are ignored by the switch chip! The user should choose the device with HW capability large enough to store all the routes or/and suppress offloading of the routes that do not fit in the HW memory.

| The 98DX3257 model is an exception, which has a feature set of the DX8000 rather than the DX3000 series. |

1 Since the total amount of routes that can be offloaded is limited, prefixes with higher netmask are preferred to be forwarded by hardware (e.g /32 /30 /29, etc.), any other prefixes that do not fit in the HW table will be processed by the CPU.
