When the interface does not have carrier but when it's put into
loopback mode (for tests), it does not make sense to not have
the carrier. So force it!

Jeff Kirsher says:

====================
This series contains updates to ixgbe and e1000e.  The ixgbe patches are
a mix of fixes, cleanup and added functionality.  The first fix is for
traffic classes, where if the mapping has changed reset the NIC.  The other
ixgbe fix resolves an issue where the device lookup neglected to do a
pci_dev_put() to decrement the device reference count.

The ixgbe cleanup was done by Josh, where the auto-negotiation variables
were renamed/cleaned up and refactored.

The remaining patches are from Bruce to do additional cleanup on e1000e as
well as bump the driver version.  Most notably is the cleanup to use the
kernel IEEE MII definitions where possible instead of the local MII
definitions.
====================

For standard IEEE MII-compatible transceivers, the kernel has generic
register and bit definitions.  Use those instead of redundant local
defines.

Do not replace references of MII_CR_SPEED_10 with BMCR_SPEED10 (0x0000)
when it is not necessary (i.e. when it is bitwise OR'ed with another
value).

Some whitespace issues in the surrounding context of the above changes are
also cleaned up.

Under heavy CPU load, changing, ring size/mtu/etc. could result in transmit
timeout, since stop-start port might take more than 10 seconds.
Calling netif_detach_device to prevent tx queue transmit timeout.

netif_detach_device() is not called under ndo_stop, because netif_carrier_off
will prevent the timeout, and device should not be marked as not present, or
else user won't be able to start it later on.

The Firmware dynamically changes flow steering hash configuration from covering

when there are no more such rules.

Supporting access to skb->pkt_type is a bit tricky if we want
to have a generic code, allowing pkt_type to be moved in struct sk_buff

pkt_type is a bit field, so compiler cannot really help us to find
its offset. Let's use a helper for this : It will throw a one time
message if pkt_type no longer starts at a byte boundary or is
no longer a 3bit field.

Makes more sense to have randomly generated address by default than to
have all zeroes. It also allows user to for example put the bond into
bridge without need to have any slaves in it.

Also note that this changes only behaviour of bonds with no slaves. Once
the first slave device is enslaved, its address will be used (no change
here).

Also, fix dev_assign_type values on the way.

Instead of jumping aroung bugs that are easily fixed just don't let them in:
affected drivers should be either fixed or have NETIF_F_HW_VLAN_FILTER
removed from advertised features.

Quick grep in drivers/net shows two drivers that have NETIF_F_HW_VLAN_FILTER
but not ndo_vlan_rx_add/kill_vid(), but those are false-positives (features
are commented out).

OTOH two drivers have ndo_vlan_rx_add/kill_vid() implemented but don't
advertise NETIF_F_HW_VLAN_FILTER. Those are:
