If i am not mistaken we don't have generic support for interrupt moderation

Of course it would be possible to modify polling to implement
generic interrupt mitigation even without hardware support, so
you get the best of the two worlds.
It seems to me that you're wasting your time if you are trying to
achieve a high throughput in FreeBSD without using an Intel Pro/1000 or
10gbe networking card.
So I don't know if anyone would really miss out if generic polling
support was completely removed from the kernel and all efforts were then
placed into improving other parts of network flow in the kernel which
need more help.
