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

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.

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.
