This patch tries to implement XDP for tun. The implementation was split into two parts: - fast path: small and no gso packet. We try to do XDP at page level before build_skb(). For XDP_TX, since creating/destroying queues were completely under control of userspace, it was implemented through generic XDP helper after skb has been built. This could be optimized in the future. - slow path: big or gso packet. We try to do it after skb was created through generic XDP helpers. Test were done through pktgen with small packets. xdp1 test shows ~41.1% improvement: Before: ~1.7Mpps After: ~2.3Mpps xdp_redirect to ixgbe shows ~60% improvement: Before: ~0.8Mpps After: ~1.38Mpps Suggested-by: NMichael S.

We use tun_alloc_skb() which calls sock_alloc_send_pskb() to allocate skb in the past. This socket based method is not suitable for high speed userspace like virtualization which usually: - ignore sk_sndbuf (INT_MAX) and expect to receive the packet as fast as possible - don't want to be block at sendmsg() To eliminate the above overheads, this patch tries to use build_skb() for small packet. We will do this only when the following conditions are all met: - TAP instead of TUN - sk_sndbuf is INT_MAX - caller don't want to be blocked - zerocopy is not used - packet size is smaller enough to use build_skb() Pktgen from guest to host shows ~11% improvement for rx pps of tap: Before: ~1.70Mpps After : ~1.88Mpps What's more important, this makes it possible to implement XDP for tap before creating skbs.

Control the size of the buffer areas via ethtool ring settings. They aren't really traditional hardware rings, but host API breaks receive and send buffer into chunks. The final size of the chunks are controlled by the host. The default value of send and receive buffer area for host DMA is much larger than it needs to be. Experimentation shows that 4M receive and 1M send is sufficient. Signed-off-by: NStephen Hemminger <sthemmin@microsoft.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

If VF is slaved to synthetic device, then any change to netvsc MAC address should be propagated to the slave device. If slave device doesn't support MAC address change then it should also be an error to attempt to change synthetic NIC MAC address. It also fixes the error unwind in the original code. If give a bad address, the old code would change the device MAC address anyway.
