Copper links with WoL or management enabled (any condition which prevents
the phy from being powered down when the interface is taken down) were
always reporting link-up when the interface had been taken down. This
is because when the interface is taken down (ifconfig ethx down),
interrupts are disabled. With no interrupts, there is no LSC interrupt,
which is normally required to set "get_link_status", which instructs the
driver to query the device for link state. The fix is to force
get_link_status to true if the interface is not up.

Until now, firewire-ohci exposed only the transmit cycle of the last
transmitted packet at each isochronous transmit complete event. This
made it impossible for FFADO (FireWire audio drivers in userspace) to
synchronize audio-out streams. The fix is to store the timestamp of
each packet in the iso xmit event. As a bonus, the transfer status is
stored too.

-Fix to re-enable the interface [by interface up command(ifup)] while the
interface is down.
-Fix to be able to down the interface by passing the last parameter
correctly to request_irq().
-Remove to read 4 extra bytes from the receiving queue after reading a
packet, even though it does not cause a predictable issue now.
-Remove occurrences of transmission done interrupt in order to tx
throughput enhancement.
-Enable IP checksum for packet receiving by setting the corresponding
hardware bit during initialization.
-Relocate ks_enable_int()/ks_disable_int() in order not to declare those
functions at the beginning of the file.
-Rename ks_enable()/_disable() to ks_enable_qmu()/ks_disable_qmu() in
order to give more meaningful names and relocate them not declaire
