  • 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 ]

  • Hi,

    This is the third submission of the network driver for PS3.
    The differences from the previous one are:

    - renamed source file names so that their prefix can match
    with the module name
    - added cbe-oss-dev@ozlabs.org line for MAINTAINER file
    - changed some in copyright comments

    If there are no more comments, please apply for 2.6.23.

    Thank you
