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.

This patch adapts qeth to handle tagged frames with VLAN-ID 0 and
with or without priority information in the tag. It enables qeth to
receive priority-tagged frames on a base interface, for example from
z/OS, without configuring an additional VLAN interface.

This code does not call deinit_card(card); in an error case, as done in
other error-handling code in the same function. But actually, the called
function init_sram can only return 0, so there is no need for the error
check at all.
init_sram is also given a void return type, and its single return statement
at the end of the function is dropped.
A simplified version of the sematic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

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()

Originally, carl9170_tx_ampdu_queue erroneously

However this bug has been fixed and the WA and
