gianfar: fix compile warning

2007-12-04T20:06:11+00:00

Eliminate an uninitialized variable warning.  The code is correct, but
a pointer to the automatic variable 'addr' is passed to dma_alloc_coherent.
Since addr has never been initialized, and the compiler doesn't know
what dma_alloc_coherent will do with it, it complains.

gianfar: Fix regression caused by new napi interface

2007-10-15T18:41:34+00:00

Protect all new napi function calls with CONFIG_GFAR_NAPI.  Otherwise
the driver will stop working when CONFIG_GFAR_NAPI disabled.

[NET]: Introduce and use print_mac() and DECLARE_MAC_BUF()

[NET] drivers/net: statistics cleanup #1 -- save memory and shrink code

2007-10-10T23:51:16+00:00

We now have struct net_device_stats embedded in struct net_device,
and the default ->get_stats() hook does the obvious thing for us.

Run through drivers/net/* and remove the driver-local storage of
statistics, and driver-local ->get_stats() hook where applicable.

This was just the low-hanging fruit in drivers/net; plenty more drivers
remain to be updated.

[NET]: Nuke SET_MODULE_OWNER macro.

2007-10-10T23:51:13+00:00

It's been a useless no-op for long enough in 2.6 so I figured it's time to
remove it.  The number of people that could object because they're
maintaining unified 2.4 and 2.6 drivers is probably rather small.

[NET]: Make NAPI polling independent of struct net_device objects.

2007-10-10T23:47:45+00:00

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.

Joseph Fannin, Scott Wood, Hans J. Koch, and Michael Chan.
