  • This patch enables the 6131 family of chips to forward DSA
    packets to other switch chips. This is needed if multiple
    DSA chips are used in a device. Without this patch the
    chip will drop any DSA packets not destined for it.

    This patch only enables the forwarding of DSA packets if
    multiple chips are used in the switch configuration.

  • The phy_mii_ioctl() function unnecessarily throws away the original ifreq.
    We need access to the ifreq in order to support PHYs that can perform
    hardware time stamping.

    Two maverick drivers filter the ioctl commands passed to phy_mii_ioctl().
    This is unnecessary since phylib will check the command in any case.

  • …it slab.h inclusion from percpu.h

    percpu.h is included by sched.h and module.h and thus ends up being
    included when building most .c files. percpu.h includes slab.h which
    in turn includes gfp.h making everything defined by the two files
    universally available and complicating inclusion dependencies.

    percpu.h -> slab.h dependency is about to be removed. Prepare for
    this change by updating users of gfp and slab facilities include those
    headers directly instead of assuming availability. As this conversion
    needs to touch large number of source files, the following script is
    used as the basis of conversion.

    http://userweb.kernel.org/~tj/misc/slabh-sweep.py

    The script does the followings.

    * Scan files for gfp and slab usages and update includes such that
    only the necessary includes are there. ie. if only gfp is used,
    gfp.h, if slab is used, slab.h.

    * When the script inserts a new include, it looks at the include
    blocks and try to put the new include such that its order conforms
    to its surrounding. It's put in the include block which contains
    core kernel includes, in the same order that the rest are ordered -
    alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
    doesn't seem to be any matching order.

    * If the script can't find a place to put a new include (mostly
    because the file doesn't have fitting include block), it prints out
    an error message indicating which .h file needs to be added to the
    file.

    The conversion was done in the following steps.

    1. The initial automatic conversion of all .c files updated slightly
    over 4000 files, deleting around 700 includes and adding ~480 gfp.h
    and ~3000 slab.h inclusions. The script emitted errors for ~400
    files.

    2. Each error was manually checked. Some didn't need the inclusion,
    some needed manual addition while adding it to implementation .h or
    embedding .c file was more appropriate for others. This step added
    inclusions to around 150 files.

    3. The script was run again and the output was compared to the edits
    from #2 to make sure no file was left behind.

    4. Several build tests were done and a couple of problems were fixed.
    e.g. lib/decompress_*.c used malloc/free() wrappers around slab
    APIs requiring slab.h to be added manually.

    5. The script was run on all .h files but without automatically
    editing them as sprinkling gfp.h and slab.h inclusions around .h
    files could easily lead to inclusion dependency hell. Most gfp.h
    inclusion directives were ignored as stuff from gfp.h was usually
    wildly available and often used in preprocessor macros. Each
    slab.h inclusion directive was examined and added manually as
    necessary.

    6. percpu.h was updated not to include slab.h.

    7. Build test were done on the following configurations and failures
    were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my
    distributed build env didn't work with gcov compiles) and a few
    more options had to be turned off depending on archs to make things
    build (like ipr on powerpc/64 which failed due to missing writeq).

    * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
    * powerpc and powerpc64 SMP allmodconfig
    * sparc and sparc64 SMP allmodconfig
    * ia64 SMP allmodconfig
    * s390 SMP allmodconfig
    * alpha SMP allmodconfig
    * um on x86_64 SMP allmodconfig

    8. percpu.h modifications were reverted so that it could be applied as
    a separate patch and serve as bisection point.

    Given the fact that I had only a couple of failures from tests on step
    6, I'm fairly confident about the coverage of this conversion patch.
    If there is a breakage, it's likely to be something in one of the arch
    headers which should be easily discoverable easily on most builds of
    the specific arch.

  • This patch converts unicast address list to standard list_head using
    previously introduced struct netdev_hw_addr. It also relaxes the
    locking. Original spinlock (still used for multicast addresses) is not
    needed and is no longer used for a protection of this list. All
    reading and writing takes place under rtnl (with no changes).

    I also removed a possibility to specify the length of the address
    while adding or deleting unicast address. It's always dev->addr_len.

    The convertion touched especially e1000 and ixgbe codes when the
    change is not so trivial.

  • The initial version of the DSA driver only supported a single switch
    chip per network interface, while DSA-capable switch chips can be
    interconnected to form a tree of switch chips. This patch adds support
    for multiple switch chips on a network interface.

    An example topology for a 16-port device with an embedded CPU is as
    follows:

    +-----+ +--------+ +--------+
    | |eth0 10| switch |9 10| switch |
    | CPU +----------+ +-------+ |
    | | | chip 0 | | chip 1 |
    +-----+ +---++---+ +---++---+
    || ||
    || ||
    ||1000baseT ||1000baseT
    ||ports 1-8 ||ports 9-16

    This requires a couple of interdependent changes in the DSA layer:

    - The dsa platform driver data needs to be extended: there is still
    only one netdevice per DSA driver instance (eth0 in the example
    above), but each of the switch chips in the tree needs its own
    mii_bus device pointer, MII management bus address, and port name
    array. (include/net/dsa.h) The existing in-tree dsa users need
    some small changes to deal with this. (arch/arm)

    - The DSA and Ethertype DSA tagging modules need to be extended to
    use the DSA device ID field on receive and demultiplex the packet
    accordingly, and fill in the DSA device ID field on transmit
    according to which switch chip the packet is heading to.
    (net/dsa/tag_{dsa,edsa}.c)

    - The concept of "CPU port", which is the switch chip port that the
    CPU is connected to (port 10 on switch chip 0 in the example), needs
    to be extended with the concept of "upstream port", which is the
    port on the switch chip that will bring us one hop closer to the CPU
    (port 10 for both switch chips in the example above).

    - The dsa platform data needs to specify which ports on which switch
    chips are links to other switch chips, so that we can enable DSA
    tagging mode on them. (For inter-switch links, we always use
    non-EtherType DSA tagging, since it has lower overhead. The CPU
    link uses dsa or edsa tagging depending on what the 'root' switch
    chip supports.) This is done by specifying "dsa" for the given
    port in the port array.

    - The dsa platform data needs to be extended with information on via
    which port to reach any given switch chip from any given switch chip.
    This info is specified via the per-switch chip data struct ->rtable[]
    array, which gives the nexthop ports for each of the other switches
    in the tree.

    For the example topology above, the dsa platform data would look
    something like this:

    static struct dsa_chip_data sw[2] = {
    {
    .mii_bus = &foo,
    .sw_addr = 1,
    .port_names[0] = "p1",
    .port_names[1] = "p2",
    .port_names[2] = "p3",
    .port_names[3] = "p4",
    .port_names[4] = "p5",
    .port_names[5] = "p6",
    .port_names[6] = "p7",
    .port_names[7] = "p8",
    .port_names[9] = "dsa",
    .port_names[10] = "cpu",
    .rtable = (s8 []){ -1, 9, },
    }, {
    .mii_bus = &foo,
    .sw_addr = 2,
    .port_names[0] = "p9",
    .port_names[1] = "p10",
    .port_names[2] = "p11",
    .port_names[3] = "p12",
    .port_names[4] = "p13",
    .port_names[5] = "p14",
    .port_names[6] = "p15",
    .port_names[7] = "p16",
    .port_names[10] = "dsa",
    .rtable = (s8 []){ 10, -1, },
    },
    },

    static struct dsa_platform_data pd = {
    .netdev = &foo,
    .nr_switches = 2,
    .sw = sw,
    };

  • Add support for the Marvell 88E6095/6095F switch chips. These
    chips are similar to the 88e6131, so we can add the support to
    mv88e6131.c easily.
