Previously we rang XDP SQ doorbell on every forwarded XDP packet.
Here we introduce a xmit more like mechanism that will queue up more
than one packet into SQ (up to RX napi budget) w/o notifying the hardware.
Once RX napi budget is consumed and we exit napi RX loop, we will
flush (doorbell) all XDP looped packets in case there are such.
I've already raised strong concerns with this approach on the RFC
patchset. Of not really taking advantage of RX bulking.
Please do not ignore this!
Sure. Your approach can fit with our plans to split the RX completion
poll loop into several stages.
I will try it when we get there.
If you can promise, that we/you will also try to other approach I'm
suggesting, then I'm fine with this patch.
Thanks.
