A queue counter can collect several statistics for one or more
hardware queues (QPs, RQs, etc ..) that the counter is attached to.
For Ethernet it will provide an "out of buffer" counter which
collects the number of all packets that are dropped due to lack
of software buffers.

The ioremap() hidden behind the io_mapping_map_wc() convenience helper
can be used for remapping multiple pages. Extend the helper so that
future callers can use it for larger ranges.

Hi David, Eric, Petri,
These two patches are very analoguous to what was already submitted for
BCMGENET and switch the SYSTEMPORT driver to utilizing __napi_schedule_irqoff()
and napi_complete_done for the RX NAPI context.
Florian Fainelli (2):
net: bcmsysport: use __napi_schedule_irqoff()
n
By using napi_complete_done(), we allow fine tuning of
/sys/class/net/ethX/gro_flush_timeout for higher GRO aggregation
efficiency for a Gbit NIC.
Check commit 24d2e4a50737 ("tg3: use napi_complete_done()") for details.

Both bcm_sysport_tx_isr() and bcm_sysport_rx_isr() run in hard irq
context, we do not need to block irq again.

This patch overloads the DSA master netdev, aka CPU Ethernet MAC to also
include switch-side statistics, which is useful for debugging purposes,
when the switch is not properly connected to the Ethernet MAC (duplex
mismatch, (RG)MII electrical issues etc.).
We accomplish this by retaining the orig
