[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 ]

skge: ignore unused error interrupts

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

The following hardware error bits only show up on Genesis chipset
and are handled elsewhere, so they can be masked off.

skge: use per-port phy locking

2007-03-23T05:48:33+00:00

Rather than a workqueue and a per-board mutex to control PHY,
use a tasklet and spinlock. Tasklet is lower overhead and works
just as well for this.

skge: fix transmitter flow control

2007-02-27T09:16:04+00:00

It looks like the skge driver inherited another bug from the sk98lin code.
If I send from 1000mbit port to a machine on 100mbit port, the switch should
be doing hardware flow control, but no pause frames show up in the statistics.

This is the analog of the recent sky2 fixes. The device needs to listen
for multicast pause frames and then not discard them.
