sb1250-mac: Driver model & phylib update

2007-10-10T23:53:47+00:00

 A driver model and phylib update.  It includes the following changes:

1. Removal of unused module options.

2. Phylib support and the resulting removal of generic bits for handling
   the PHY.

3. Proper reserving of device resources and using ioremap()ped handles
   to access MAC registers rather than platform-specific macros.

4. Handling of the device using the driver model.

sb1250-mac.c: De-typedef, de-volatile, de-etc...

2007-10-10T23:53:47+00:00

 Remove typedefs, volatiles and convert kmalloc()/memset() pairs to
kcalloc().  Also reformat the surrounding clutter.

[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]: 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.

Bug fixes from Thomas Graf, Roland Dreier, Peter Zijlstra,
Joseph Fannin, Scott Wood, Hans J. Koch, and Michael Chan.

[ Ported to current tree and all drivers converted.  Integrated
  Stephen's follow-on kerneldoc additions, and restored poll_list
  handling to the old style to fix mutual exclusion issues.  -DaveM ]

potential compiler error, irqfunc caller sites update

2007-07-06T17:23:43+00:00

In 7d12e780e003f93433d49ce78cfedf4b4c52adc5 David Howells performed
this evolution:
 "IRQ: Maintain regs pointer globally rather than passing to IRQ handlers"

He correctly updated many of the function definitions that were using this
extra regs pointer parameter but forgot to update some caller sites of
those functions.  The reason the modifications was not properly done on all
drivers is that some drivers were rarely compiled because they are for
AMIGA, or that some code sites were inside #ifdefs where the option is not
set or inside #if 0.

Here is the semantic patch that found the occurences
and fixed the problem.

@ rule1 @
identifier fn;
identifier irq, dev_id;
typedef irqreturn_t;

add NAPI support to sb1250-mac.c

2007-04-28T15:01:07+00:00

Patch to add NAPI support to sb1250-mac.c (rev 2).  This patch differs from
the last in that the NAPI support isn't marked as experimental, nor is it
configurable (ie.  once applied - NAPI is enabled all the time).  This was
based on feedback from Ralf and others.
