The tg3 NVRAM selftest actually fails when validating the checksum of
the legacy NVRAM format. However, the test still reported success
because the last update of the return code was a success from the NVRAM
reads. This patch fixes the code so that the error return code defaults
to a failure status. Then the patch fixes the reason why the checsum
validation failed.

flush_scheduled_work() is on its way out. This patch contains simple

Directly cancel the used works on driver detach and flush them in
other cases.
The conversions are mostly straight forward and the only dangers are,
* Forgetting to cancel/flush one or more used works.
* Cancelling when a work should be flushed (ie. the work must be
executed once scheduled whether the driver is detaching or not).

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.
