The keys used for the hardware RSS topelitz hash are of type __be32
where the values provided by the driver are from array of u32,
this triggered sparse warning on incorrect type in assignment as of different base types.
Since these values are picked randomly,
the fix is to transform the key to __be32 by executing cpu_to_be_32()

Localized the pdev->dev, and using dma_map instead of pci_map
There are multiple map/unmap operations on data path,
optimizing those by saving redundant pointer access.
Those places were identified as hot-spots when running kernel profiling
during some benchmarks.
The fixes had most impact when testing packet rate with small packets,
reducing several % from CPU load, and in some case being the difference
between reaching wire speed or being CPU bound.

With runtime PM, if the ethernet cable is disconnected, the device is
transitioned to D3 state to conserve energy. If the system is shutdown
in this state, any register accesses in rtl_shutdown are dropped on
the floor. As the device was programmed by .runtime_suspend() to wake
on link changes, it is thus brought back up as soon as the link recovers.

Resuming every suspended device through the driver core would slow things
down and it is not clear how many devices really need it now.

Original report and D0 transition patch by Sameer Nanda. Patch has been
changed to comply with advices by Rafael J. Wysocki and the PM folks.

In case all event queues are broken for some reason, this means it
will only take about a second to check them all, rather than up to 32
seconds.  This may also speed up testing in the successful case.

IRQ latency can be ridiculously high for various reasons, so our
current timeouts of 100 ms or 10 ms are too short.

Change the IRQ and event tests to use polling loops starting with a
delay of 1 tick and doubling that if necessary up to a maximum total
delay of approximately 1 second.

Raise the loopback packet RX timeout to 1 second.

RX and TX completions on the same event queue are generally not associated
with the same flows.  The inclusion of TX completions in the adaptive IRQ
score is more of a source of noise rather than useful feedback.  Therefore,
do not include them in the score, and adjust the default threshold scores
down.
