For the operations
	get-tx-csum
	get-sg
	get-tso
	get-ufo
the default ethtool_op_xxx behavior is fine for all drivers, so we
permit op==NULL to imply the default behavior.

This provides a more uniform behavior across all drivers, eliminating
ethtool(8) "ioctl not supported" errors on older drivers that had
not been updated for the latest sub-ioctls.

The ethtool_op_xxx() functions are left exported, in case anyone
wishes to call them directly from a driver-private implementation --
a not-uncommon case.  Should an ethtool_op_xxx() helper remain unused
for a while, except by net/core/ethtool.c, we can un-export it at a
later date.

The cxgb3 driver is incorrectly configuring the HW CQ context for CQ's
that use overflow-avoidance.  Namely the RDMA control CQ.  This results
in a bad DMA from the device to bus address 0.  The solution is to set
the CQ_ERR bit in the context for these types of CQs.

Several devices have multiple independant RX queues per net
device, and some have a single interrupt doorbell for several
queues.

In either case, it's easier to support layouts like that if the
structure representing the poll is independant from the net
device itself.

The signature of the ->poll() call back goes from:

	int foo_poll(struct net_device *dev, int *budget)

to

	int foo_poll(struct napi_struct *napi, int budget)

The caller is returned the number of RX packets processed (or
the number of "NAPI credits" consumed if you want to get
abstract).  The callee no longer messes around bumping
dev->quota, *budget, etc. because that is all handled in the
caller upon return.

The napi_struct is to be embedded in the device driver private data
structures.

Furthermore, it is the driver's responsibility to disable all NAPI
instances in it's ->stop() device close handler.  Since the
napi_struct is privatized into the driver's private data structures,
only the driver knows how to get at all of the napi_struct instances
it may have per-device.

With lots of help and suggestions from Rusty Russell, Roland Dreier,
Michael Chan, Jeff Garzik, and Jamal Hadi Salim.

Due to a HW issue, our current scheme to transition the connection from
streaming to rdma mode is broken on the passive side.  The firmware
and driver now support a new transition scheme for the passive side:

 - driver posts rdma_init_wr (now including the initial receive seqno)
 - driver posts last streaming message via TX_DATA message (MPA start
   response)
 - uP atomically sends the last streaming message and transitions the
   tcb to rdma mode.
 - driver waits for wr_ack indicating the last streaming message was ACKed.

NOTE: This change also bumps the required firmware version to 4.3.
