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.

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).

When an MCC cmd is issued (via a netdev/ethtool op)
while the device is not open, the MCC CQ gets processed but the EQ
is not processed (as isr is not registered.) This can cause the EQ
to become full. So, while the device is not open, CQ must not be re-armed
to prevent EQ entries.

Currenlty all cmds use the blocking MCC mbox to post cmds. An mbox cmd is protected
via a spin_lock(cmd_lock) and not spin_lock_bh() as it is undesirable
to disable BHs while a blocking mbox cmd is in progress (and take long to finish.)
This can lockup a cmd in progress in process context. Instead cmds that may be
called in BH context must use the MCC queue to post cmds. The cmd completions
are rcvd in a separate completion queue and the events are placed in the tx-event
queue.
