Cheap switch with a couple 100G

The argument should be 50G is cheaper than 40G.

Because serdes is 25G typically, you get 25, 50, 100 without gearboxes
and retimers, so less pincount, less thermal, higher density, lower
cost.

But BOM impact to pricing isn't high anyhow, unless we're talking
about massive port counts.

If box DOES support 10GE and 40GE then the cost benefit is not there,
so you need to be targeting quite specific use case, use-case large
scale DCs are targeting.
