This patch adds multiple RX queue support to be2net. There are
upto 4 extra rx-queues per port into which TCP/UDP traffic can be hashed into.
Some of the ethtool stats are now displayed on a per queue basis.

Up until now the tg3 driver would call netif_napi_add() for the maximum
number of NAPI instances the driver could use.  The problem is that
netpoll could call tg3_poll() on instances that are not active.  The net
effect is that the driver will crash attempting to dereference
uninitialized pointers.

The fix is to only allocate as many NAPI instances as the driver would
use in tg3_open() and deleted them in tg3_close().

Most e1000e parts support batching writebacks.  The problem with this is
that when some of the TADV or TIDV timers are not set, Tx can sit forever.

This is solved in this patch with write flushes using the Flush Partial
Descriptors (FPD) bit in TIDV and RDTR.

This improves bus utilization and removes partial writes on e1000e,
particularly from 82571 parts in S5500 chipset based machines.

Only ES2LAN and 82571/2 parts are included in this optimization, to reduce
testing load.

This patch contains the following DCA improvements to myri10ge:

1) Finally move myri10ge to use dca3 API

2) Disable PCIe relaxed ordering when enabling DCA on
     myri10ge.  This provides a performance boost on Nehalem
     based Xeons

3) Make sure to properly initialize NIC's DCA state when it is enabled,
     rather than giving the NIC a bogus tag (0) and waiting for
     the first received packet to trigger an update.  Not using a
     real tag can cause hardware exceptions on some motherboards
     when a CPU socket is empty.

3) Always update the cached CPU when our interrupt affinity changes
     so as to avoid excessive calls to dca3_get_tag()

This patch removes some cruft, which survived
the RFC review phase.

Originally, carl9170_tx_ampdu_queue erroneously
dropped a lot of frames. As a result the ampdu
scheduler bogged down quite frequently and the
affected BA session timed out.

However this bug has been fixed and the WA and
its debugfs counter is no longer useful.

iwl3945's scan_completed calls into the mac80211 stack which triggers a
warn on if there is no scan outstanding.

This can be avoided by not calling scan_completed but abort_scan in
iwl3945_request_scan  in the done: branch of the function which is used
as an error out.

The done: branch seems to be an error-out branch, as, for example, if
iwl_is_ready(priv) returns false  the done: branch is executed.

NOTE:
I'm not familiar with the driver at all.
I just quickly scanned as a reaction to

https://bugzilla.kernel.org/show_bug.cgi?id=17722

the users of scan_completed in the  iwl3945 driver and noted the odd
discrepancy between the comment above this instance and the comment in
