With the recent changes to tx mutiqueue, igb/ixgbe/e1000e was not calling
netif_tx_start_all_queues() before calling netif_tx_wake_all_queues().
This causes an issue during loading of the driver.
In addition, updated e1000e to use the updated tx mutliqueue api.

This effectively "flips the switch" by making the core networking
and multiqueue-aware drivers use the new TX multiqueue structures.
Non-multiqueue drivers need no changes. The interfaces they use such
as netif_stop_queue() degenerate into an operation on TX queue zero.
So everything "just works" for them.
Code that really wants to do "X" to all TX queues now invokes a
routine that does so, such as netif_tx_wake_all_queues(),
netif_tx_stop_all_queues(), etc.
pktgen and netpoll required a little bit more surgery than the others.
In particular the pktgen changes, whilst functional, could be largely
improved. The initial check in pktgen_xmit() will sometimes check the
wrong queue, which is mostly harmless. The thing to do is probably to
invoke fill_packet() earlier.
The bulk of the netpoll changes is to make the code operate solely on
the TX queue indicated by by the SKB queue mapping.
Setting of the SKB queue mapping is entirely confined inside of
net/core/dev.c:dev_pick_tx(). If we end up needing any kind of
special semantics (drops, for example) it will be implemented here.
Finally, we now have a "real_num_tx_queues" which is where the driver
indicates how many TX queues are actually active.
With IGB changes from Jeff Kirsher.

There is no need for a feature bit for something that
can be tested by simply checking the TX queue count.

Currently VLAN filtering is enabled when the first VLAN is added.
Obviously before that there's no point in receiving any VLAN packets.
Now that we disable VLAN filtering in promiscous mode, we can keep
the VLAN filters enabled the remaining time.

Change igb from using a series of boolean operators to using a single flags
value that contains a number of different bit flags for all the different
features of the adapter.
This patch also adds WOL support for quad port adapters.

We can remove a clunky workaround for not having the hardware
strip the CRC. 82575 silicon as well as the older PCI Express
e1000e hardware all work OK in this respect.

Add DCA support in the similar method that it was added to the ixgbe
driver recently. DCA allows the network device to put data in the
CPU cache and notify the chipset of that event. This reduces cache
misses during receives.

This code adds multiple Tx queue infrastructure much like we
previously did in ixgbe. The MSI-X vector mapping is the bulk of
the change.
IAM can now be safely enabled and we've verified that it does
work correctly. We can also eliminate the tx ring lock.
