dsa: add switch chip cascading support

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,
};

powerpc 4xx EMAC driver: device name reported on timeout is not correct

Hi,

IBM EMAC driver performs device reset (drivers/net/ibm_newemac/core.c:
emac_probe() -> emac_init_phy() -> emac_reset()) before registering
appropriate net_device (emac_probe() -> register_netdev()), so
net_device name contains raw format string during EMAC reset ("eth%d").

If the case of reset timeout, emac_report_timeout_error() function is
called to report an error. The problem is this function uses net_device
name to report device related, which is not correct, as a result in the
kernel log buffer we see:

eth%d: reset timeout

The solution is to print device_node full_name instead. After applying
the patch proposed, error string is like the following:

net: remove useless prefetch() call

There is no gain using prefetch() in dev_hard_start_xmit(), since
we already had to read ops->ndo_select_queue pointer in dev_pick_tx(),
and both pointers are probably located in the same cache line.

This prefetch call slows down fast path because of a stall in address
computation.

net: reorder struct Qdisc for better SMP performance

dev_queue_xmit() needs to dirty fields "state", "q", "bstats" and "qstats"

On x86_64 arch, they currently span three cache lines, involving more
cache line ping pongs than necessary, making longer holding of queue spinlock.

We can reduce this to one cache line, by grouping all read-mostly fields
at the beginning of structure. (Or should I say, all highly modified fields
at the end :) )

Before patch :

offsetof(struct Qdisc, state)=0x38
offsetof(struct Qdisc, q)=0x48
offsetof(struct Qdisc, bstats)=0x80
offsetof(struct Qdisc, qstats)=0x90
sizeof(struct Qdisc)=0xc8

After patch :

offsetof(struct Qdisc, state)=0x80
offsetof(struct Qdisc, q)=0x88
offsetof(struct Qdisc, bstats)=0xa0

packets with hardware checksum on, it chokes with an

There are times when we'd like to send these packets

smsc911x: reset last known duplex and carrier on open

smsc911x_phy_adjust_link is called periodically by the phy layer (as
it's run in polling mode), and it only updates the hardware when it sees
a change in duplex or carrier.  This patch clears the last known values
every time the interface is brought up, instead of only when the module
is loaded.

Without this patch the adjust_link function never updates the hardware
after an ifconfig down; ifconfig up.  On a full duplex link this causes
the tx error counter to increment, even though packets are correctly
transmitted, as the default MAC_CR register setting is for half duplex.

The tx errors are "no carrier" errors, which should be ignored in
full-duplex mode.  When MAC_CR is set to "full duplex" mode they are
correctly ignored by the hardware.

Note that even with this patch the tx error counter can increment if
packets are transmitted between "ifconfig up" and the first phy poll
interval.  An improved solution would use the phy interrupt with phylib,
but I haven't managed to make this work 100% robustly yet.
