staging: comedi: addi_tcw.h: provide generic defines for the ADDI-DATA TCW
The TCW (timer/counter/watchdog) devices in the various ADDI-DATA drivers
use a common register map definition. Provide a common generic define for
these registers so they don't have to be replicated in each driver.

staging: comedi: addi_apci_1564: fix timer iobase for all PLD revisions

staging: comedi: addi_apci_1564: detect PLD revision for I/O mapping
The APCI-1564 has different I/O mapping depending on if the PLD revision is
Rev 1.0 or Rev 2.x. The revision can be determined by reading the EEPROM
register at offset 0x00 of PCI BAR 0 and checking the value of bits 7 to 4.
Add this check to apci1564_auto_attach(). Currently this driver is coded
to work with the Rev 2.x I/O mapping. For now, fail the attach if a Rev 1.0
PLD is detected. Document the I/O mapping for both revisions.

staging: octeon-ethernet: drop multiple NAPI instances
Octeon Ethernet driver is currently trying to wake up multiple
CPU cores for parallel NAPI processing when needed, to cope
with the fact that all network interfaces are handled through
the same receive queue processed by a single core/interrupt
(see http://marc.info/?l=linux-kernel&m=137209784914565&w=2).
This partially overlaps with generic RPS functionality.
Commit a6a39a7fcff5 ("staging: octeon-ethernet: disable load balance

when RPS is enabled. Let's delete this code altogether as it has issues
like packet reordering and potential problems with CPU offlining/onlining.
