[iovisor-dev] [PATCH RFC 11/11] net/mlx5e: XDP TX xmit more

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

[iovisor-dev] [PATCH RFC 10/11] net/mlx5e: XDP TX forwarding support

Adding support for XDP_TX forwarding from xdp program. Using XDP, now user can loop packets out of the same port. We create a dedicated TX SQ for each channel that will serve XDP programs that return XDP_TX action to loop packets back to the wire directly from the channel RQ RX path. For that RX

[iovisor-dev] [PATCH RFC 04/11] net/mlx5e: Build RX SKB on demand

For non-striding RQ configuration before this patch we had a ring with pre-allocated SKBs and mapped the SKB->data buffers for device. For robustness and better RX data buffers management, we allocate a page per packet and build_skb around it. This patch (which is a prerequisite for XDP) will
