If skb_clear_hash() was invoked due to mangling of relevant headers and BPF program needs skb->hash later on, we can add a helper to trigger hash recalculation via bpf_get_hash_recalc(). The helper will return the newly retrieved hash directly, but later access can also be done via skb context again through skb->hash directly (inline) without needing to call the helper once more.

Extremely useful for setting packet type to host so i dont have to modify the dst mac address using pedit (which requires that i know the mac address) Example usage: tc filter add dev eth0 parent ffff: protocol ip pref 9 u32 \ match ip src 5.5.5.5/32 \ flowid 1:5 action skbedit ptype host This will tag all packets incoming from 5.5.5.5 with type PACKET_HOST Signed-off-by:

Jiri Pirko says: ==================== mlxsw: Lay the groundwork for the introduction of router interfaces This is first patchset on a way to introduce ipv4 routing offload support in mlxsw driver.

ip2me: To instruct HW to send trapped ip2me traffic to kernel, we have to add this trap. Selection ip2me traffic is introduced later on in this set. ARPs: We are going to stop flooding to CPU port when netdev isn't bridged and only get packets destined to the netdev's IP address and certain control packets. Add traps for ARP request (broadcast) and response (unicast) in order to get these to the CPU and resolve neighbours. host miss: If a packet is routed through a directly connected route and its destination IP is not in the device's neighbour table, then we need to trap it to CPU. This will cause the host to resolve the MAC of the neighbour, which will be eventually programmed to the device's table. router ingress: In order to trap packets in router part. Signed-off-by:

When removing packet traps we should use action 'discard' instead of 'forward', as some trap IDs we'll add cannot be configured with the later. However, result is the same, as packets are not trapped to the CPU. In the future we will be able to reverse the operation properly by detaching the trap group from the CPU. Signed-off-by:

When enabling the router in the device we will represent L3 netdevs using router interfaces (RIFs). These will be specified whenever programming routes or neighbours on the netdev. Introduce the basic RIF infrastructure which allows one to lookup a RIF by its netdev. Later patches in the series will extend this, but the basic routines are needed now in order to direct traffic to CPU. Pointers to the RIF structs are stored in an array indexed by the RIF's number. This will allow us to efficiently update the kernel's neighbour table when regularly dumping the device's table. Signed-off-by:

During ports initialization a net device is registered for each available port, which implies the port is usable. However, a port is only usable after the different parts of the device (e.g. flooding, buffers) are initialized. This is especially important now, when we must initialize the router before the ports, as otherwise the device can't be initialized. Solve that by initializing the switch ports at the end of init sequence. Also, remove an unnecessary warning about port up/down events, which would otherwise be invoked whenever removing the driver, as ports are removed before unregistering the listener for these events.
