Based on original patch/work from Jean Delvare <jdelvare@suse.de>
Synchronize all IRQs when in MSI-X IRQ mode.

Jean's original patch hard coded the sync with the 3 possible vectors,
this patch incorporates more flexibility for the future and aligns
with how igb stores the number of vectors into the adapter structure.

The pm_qos_add_request call has to register the pm_qos request with the pm_qos
susbsystem before first use of the pm_qos request via
pm_qos_update_request.

As pm_qos changed to use plists there is no benefit in registering and
unregistering the pm_qos request on ifup/ifdown and thus we move the
registering into e1000_open and the unregistering in e1000_close.

This fixes the following warning:

smp_mb() inside tg3_tx_avail() is used twice in the normal
tg3_start_xmit() path (see illustration below).  The full memory
barrier is only necessary during race conditions with tx completion.
We can speed up the tx path by replacing smp_mb() in tg3_tx_avail()
with a compiler barrier.  The compiler barrier is to force the
compiler to fetch the tx_prod and tx_cons from memory.

In the race condition between tg3_start_xmit() and tg3_tx(),
we have the following situation:

tg3_start_xmit()                       tg3_tx()
    if (!tg3_tx_avail())
        BUG();

    ...

    if (!tg3_tx_avail())
        netif_tx_stop_queue();         update_tx_index();
        smp_mb();                      smp_mb();
        if (tg3_tx_avail())            if (netif_tx_queue_stopped() &&
            netif_tx_wake_queue();         tg3_tx_avail())

With smp_mb() removed from tg3_tx_avail(), we need to add smp_mb() to
tg3_start_xmit() as shown above to properly order netif_tx_stop_queue()
and tg3_tx_avail() to check the ring index.  If it is not strictly
ordered, the tx queue can be stopped forever.

This improves performance by about 3% with 2 ports running
bi-directional 64-byte packets.
