The driver was calling the set Rx mode function for every multicast
filter set by the VF. When starting many VMs where each might have
multiple VLAN interfaces this would result in the function being
called hundreds or even thousands of times. This is unnecessary
for the case of the imperfect filters used in the MTA and has been
streamlined to be more efficient.

The driver is unnecessarily writing values to VLAN control registers.
These writes already done elsewhere and are superfluous here.

Add support for the "ip link set" and "ip link show" commands that allow
configuration of the virtual functions' MAC and port VLAN via user space
command line.

Add a boolean parameter to ixgbe-set_vmolr so that the caller can
specify whether the pool should accept untagged packets. Required
for a follow on patch to enable administrative configuration of port
VLAN for virtual functions.

Inadequate coordination between the PF driver and the VF driver results
in tx hangs in the VF driver when you perform certain actions that will
lead to a re-init of the PF. Add feature to notify active VFs when the PF
is about to re-initialize so that the VFs can take appropriate action.
