I fully believe and expect there are platforms where it would not be
viable, especially 'l3 switch' type devices which make lot of
assumptions to reduce cost. But I'd be surprised if high touch devices
like ezchip, trio, solar (or what ever the huawei chip was called),
fp3 etc. couldn't do it.
Naively it feels like classify on ingress NPU, inject the
classification information on cell headers over fabric, egress NPU
then produces l2 rewrite information, taking into consideration the
classification found on cell headers.
