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.

The ONLINE registers can return 0xFFFFFFFF on more than one
occassion. On systems that care, reading these registers could
lead to problems.
So the new code decides that the ASIC has encountered and error
by reading the UE_STATUS_LOW/HIGH registers. AND them with
the mask values and a non-zero result indicates an error.

If a new request for get stats is fired before the response for

In tx/mcc polling, napi_complete() is being incorrectly called
before reaping tx completions. This can cause tx compl processing
to be scheduled on another cpu concurrently which can result in a panic.
This if fixed by calling napi complete() after tx/mcc compl processing
but before re-enabling interrupts (via a cq notify).

while the device is not open, the MCC CQ gets processed but the EQ
