I test our devices on an Embedded system.
We find the throughput is low.
And it is caused by the weight.
Our NAPI function often uses the whole budget.
Finally, we increase the weight, and the throughput is good.

Could it possibly be related to handling of aggregation?
Problem must lay somewhere in USB specifics, since as I said
there are 100Gbps devices running fine with budget of 64.

I think it depends on the platform.
Most of the platforms don't have the same situation.
Besides, I think the platform with 100Gbps device may
have faster CPU than that one which I test.

What would happen, if I set the weight to 256 on the platform
which runs well for the weight of 64?
Doesn't it only influence the slow platform?
