Make dsmark work properly with non-linear and cloned skb's
Before modifying the header, it needs to check that skb header is
writeable.
Note: this makes the assumption, that if it queues a good skb
then a good skb will come out of the embedded qdisc.

The code is already gone for about half a year, the config option
has been kept around to select the replacement options for easier
upgrades. This seems long enough, people upgrading from older
kernels will have to reconfigure a lot anyway.

When the lower device's carrier is off, the macvlan devices's
carrier state should be checked to decide whether it needs to
be turned off. Currently the lower device's state is checked
a second time.
This still works, but unnecessarily tries to turn off the
carrier when its already off.

I think, that we can make this code flow easier to understand
by introducing the vlan_set_encap_proto() function (I hope the
name is good) to setup the skb proto and merge the paths calling
netif_rx() together.

Keep track of the number of VLAN devices in a vlan group. This allows
to have the caller sense when the group is going to be destroyed and
stop using it, which in turn allows to remove the wrapper around
unregister_vlan_dev for the NETDEV_UNREGISTER notifier and avoid
iterating over all possible VLAN ids whenever a device in unregistered.
Also fix what looks like a use-after-free (but is actually safe since
we're holding the RTNL), the real_dev reference should not be dropped
while we still use it.

The GET_VLAN_INGRESS_PRIORITY_CMD/GET_VLAN_EGRESS_PRIORITY_CMD ioctls are
not implemented and won't be, new functionality will be added to the netlink
interface. Remove the code and make the ioctl handler return -EOPNOTSUPP
for unknown commands instead of -EINVAL.
Also remove a comment about passing unknown commands to the underlying
device, that doesn't make any sense since its a VLAN specific ioctl and
if its not implemented here, its implemented nowhere.

The printk about ingress qdisc registration error can't be triggered
under normal circumstances. Since register_qdisc only fails for two
identical registrations, the only way to trigger it is by loading the
sch_ingress modules multiple times under different names, in which
case we already return -EEXIST to userspace.

When using a stir4200-based USB adaptor to talk to a device that uses
an mcp2150, the stir4200 sometimes drops an incoming frame causing the
mcp2150 to try and retransmit the lost frame. In this combination, the
next frame received from the mcp2150 is often invalid - either an
empty i:rsp or an IrCOMM i:rsp with an invalid clen. These corner
cases are now checked.
