A recent change makes it necessary to set get_link_status to ensure that
the driver fetches the correct, refreshed value for link status and speed
when it has changed in the physical function device.

In ixgbevf_get_ringparam we could run into a NULL pointer dereference
if the rings were not allocated when we attempted the call. To prevent
that we can just access the tx/rx_ring_count values instead of attempting
to access the rings to get the count.
This change corrects a memory leak and memory corruption in
ixgbevf_set_ringparam.
The memory leak was due to us not freeing the resources from the ring
before overwriting them. This change corrects the memory leak by making
certain to call ixgbe_free_tx/rx_resources on the rings prior to freeing
them.
The memory corruption was because we were replacing the rings but not
updating the q_vectors. It addresses the memory corruption by leaving the
rings in place and instead just copying the contents of the new rings into
the existing rings.

This change adds the netdev to the ring structure. This allows for a
quicker transition from ring to netdev without having to go from ring to
adapter to netdev.

Currently the VF driver is processing all of the transmits in interrupt
context. This can be messy since the Rx is all handled in NAPI and this
may result in interrupts being disabled. In order to resolve this move all
of the Tx packet processing into NAPI and combine all of the interrupt and
polling routines into just a pair of functions.

There is a large amount of code present in this driver to support features
that either do no exist or are not supported such ask packet split, DCA, or
RSC. This patch strips out almost all of that code and in the case of
conditionals based on unused flags I am flatting the code out to just the
path that would have been selected.

The X540 10Gig controller is capable of linking at 100Mbits - add
support for reporting that link speed.

Per discussion with Ben Hutchings and David Miller, go through and
remove assignments of "N/A" to fw_version in various drivers'
.get_drvinfo routines. While there clean-up some use of bare
constants and such.

Per comments from Ben Hutchings on a previous patch, sweep the floors
a little removing unnecessary assignments of zero to fields of struct
ethtool_ringparam in driver code supporting ethtool -g.

Private rx_csum flags are now duplicate of netdev->features & NETIF_F_RXCSUM.
Removing this needs deeper surgery.
Since ixgbevf doesn't change hardware state on RX csum enable/disable
its reset is avoided.
Things noticed:
- HW VLAN acceleration probably can be toggled, but it's left as is
- the resets on RX csum offload change can probably be avoided
- there is A LOT of copy-and-pasted code here
