Extremely useful for setting packet type to host so i dont

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.

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.

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.

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.

We are going to assign router interfaces (RIFs) to netdevs if an IPv4
address was assigned to them. If one was assigned to a port netdev, this
will translate to the PVID vPort being member in a RIF.

While it's possible for a LAG slave to have an IP address, we can't have
a vPort being member in two FIDs (assuming the LAG device will be
put in bridge / assigned an IP address).

Solve that by making the PVID vPort leave any FID it might be a member
in when joining / leaving LAG.

Note that the PVID vPort is the only vPort that can be present on the
port when it's put under LAG.

When VLAN devices are created on top of LAG, their underlying vPorts are
configured correctly with LAG membership.

However, the PVID vPort is implicit and already present when the port
netdev is put under LAG, so its LAG membership is never set. Set it
correctly when joining / leaving LAG.

This didn't matter until now, but we are going to introduce support for
router interfaces (RIFs), which need to take into account LAG membership.

When port isn't bridged it is still possible to invoke switchdev ops and
configure the device's VLAN filters.

However, this will require us to use different Router InterFaces (RIFs)
for the same netdev, instead of one per-netdev as with any other
configuration.

Taking the above into account and the fact that this functionality is
questionable with regards to the device's normal use-case, remove it and
instead return an error.

Port netdevs (e.g. swXpY) that are not bridged are represented in the
device using a vPort with VID=PVID=1 (the PVID vPort), as untagged
packets entering the switch are internally tagged with the PVID VLAN.
When these packets are routed through a different port netdev they
should egress untagged.

This wasn't a problem until now, as non-bridged traffic only originated
from the CPU, which transmits packets out of the port as-is.

When a vPort is created with VID 1 mark it as egress untagged.

To prevent that, we call function reset on the 1st PF open before any VF
can be activated.  On subsequent PF opens (with possibly some active VFs),
a bit has been set and we'll skip the function reset.  VF driver will
always do function reset on every open.  If there is an AER event, we will
