  • Fix problems detected by sparse:
    1. whole chunk of MAC code was for defined and never used
    2. hook for running ext intr in workqueue wasn't being used

  • 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.

  • 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.

  • 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.

    Stephen's follow-on kerneldoc additions, and restored poll_list
    handling to the old style to fix mutual exclusion issues. -DaveM ]

  • Many drivers had code that did kill_vid, but they weren't doing vlan
    filtering. With new API the stub is unneeded unless device sets
    NETIF_F_HW_VLAN_FILTER.

    Bad habit: I couldn't resist fixing a couple of nearby style things
    in acenic, and forcedeth.

  • This patch splits the vlan_group struct into a multi-allocated struct. On
    x86_64, the size of the original struct is a little more than 32KB, causing
    a 4-order allocation, which is prune to problems caused by buddy-system
    external fragmentation conditions.

    I couldn't just use vmalloc() because vfree() cannot be called in the
    softirq context of the RCU callback.

  • Chelsio without NAPI enabled has been broken (won't compile) since
    3de00b89 ("chelsio: NAPI speed improvement"):

    drivers/net/chelsio/sge.c: In function `t1_interrupt`:
    drivers/net/chelsio/sge.c:1716: error: `Q` undeclared (first use in this function)

    The change below seems to add back in the declaration and
    initialization of `Q` that was removed by mistake, and at least makes
    the driver compile for me, although I have no hardware and hence no
    way to test whether this actually works.

  • This driver tries to enable/disable NAPI at runtime, but
    does so in an unsafe manner, and the NAPI interrupt handling is
    a mess. Replace it with a compile time selected NAPI implementation.
