When setting MTU, actually what we do is configuring the max frame size
for the hardware. ETH_HLEN、ETH_FCS_LEN and VLAN_HLEN must need to be
considered. And the frame size which is less than the default value
should not be set to the hardware. Because in the hardware, the the max
frame size not only controls the RX packet size, but also controls the
TX packet size. the RX packets whose size are greater than the setting
value will be dropped.

This patch fixes the bug setting a error max frame size to hardware.

In exisiting code, the way to detect if driver/client reset should
be executed or if hardware should be be soft resetted was overly
complex.

Existing code use to read the interrupt status register from task
context to figure out if the interrupt source event was reset and
then use clear the interrupt source for reset while waiting for the
hardware to finish the reset. This behaviour again was confusing
and overly complex in terms of the flow.

This patch simplifies the handling of the requested reset and the
pending reset(i.e. reset which have already been asserted by the
software and hardware has acknowledged back to driver that it is
processing the hardware reset through interrupt)

The reset interrupt event shares common miscellaneous interrupt
Vector 0. In the existing reset interrupt handling we disable
the Vector 0 interrupt in misc interrupt handler and re-enable
them later in context to common service task.

This also means other event sources like mailbox would also be
deferred or if the interrupt event was due to mailbox(which shall
be supported for VF soon), it could delay the reset handling.

This patch reorganizes the reset interrupt handling logic and
makes it more fair to other events.
