2a6ba39ad6 can: sja1000: legacy SJA1000 ISA bus driver
This patch adds support for legacy SJA1000 CAN controllers on the ISA
or PC-104 bus. The I/O port or memory address and the IRQ number must
be specified via module parameters:

  insmod sja1000_isa.ko port=0x310,0x380 irq=7,11

for ISA devices using I/O ports or:

  insmod sja1000_isa.ko mem=0xd1000,0xd1000 irq=7,11

for memory mapped ISA devices.

Indirect access via address and data port is supported as well:

  insmod sja1000_isa.ko port=0x310,0x380 indirect=1 irq=7,11

Here is a full list of the supported module parameters:

  port:I/O port number (array of ulong)
  mem:I/O memory address (array of ulong)
  indirect:Indirect access via address and data port (array of byte)
  irq:IRQ number (array of int)
  clk:External oscillator clock frequency (default=16000000 [16 MHz])
      (array of int)
  cdr:Clock divider register (default=0x48 [CDR_CBP | CDR_CLK_OFF])
      (array of byte)
  ocr:Output clock register (default=0x18 [OCR_TX0_PUSHPULL])
      (array of byte)

Note: for clk, cdr, ocr, the first argument re-defines the default
for all other devices, e.g.:

 insmod sja1000_isa.ko mem=0xd1000,0xd1000 irq=7,11 clk=24000000

is equivalent to

 insmod sja1000_isa.ko mem=0xd1000,0xd1000 irq=7,11 \
                       clk=24000000,24000000

fab4e76373 WAN: dscc4: Fix warning pointing out a bug.
Noticed by Stephen Rothwell:

	Today's linux-next build (x86_64 allmodconfig gcc-4.4.0)
	produced this warning:

	drivers/net/wan/dscc4.c: In function 'dscc4_rx_skb':
	drivers/net/wan/dscc4.c:670: warning: suggest parentheses around comparison in operand of '|'

	which actually points out a bug, I think.  It is doing
		(x & (y | z)) != y | z
	when it probably means
		(x & (y | z)) != (y | z)

	Introduced by commit 5de3fcab91
	("WAN: bit and/or confusion").

2c11455321 macvlan: add multiqueue capability
macvlan devices are currently not multi-queue capable.

We can do that defining rtnl_link_ops method,
get_tx_queues(), called from rtnl_create_link()

This new method gets num_tx_queues/real_num_tx_queues
from lower device.

macvlan_get_tx_queues() is a copy of vlan_get_tx_queues().

Because macvlan_start_xmit() has to update netdev_queue
stats only (and not dev->stats), I chose to change
tx_errors/tx_aborted_errors accounting to tx_dropped,
since netdev_queue structure doesnt define tx_errors /
tx_aborted_errors.

8de8b2e634 ixgbe: Add support for multiple Tx queues for FCoE in 82599
This patch adds support for multiple transmit queues to the Fiber Channel
over Ethernet (FCoE) feature found in 82599. Currently, FCoE has multiple
Rx queues available, along with a redirection table, that helps distribute
the I/O load across multiple CPUs based on the FC exchange ID. To make
this the most effective, we need to provide the same layout of transmit
queues to match receive.

Particularly, when Data Center Bridging (DCB) is enabled, the designated
traffic class for FCoE can have dedicated queues for just FCoE traffic,
while not affecting any other type of traffic flow.

3eb0027594 NET: Fix possible corruption in bpqether driver
The bpq ether driver is modifying the data art of the skb by first
dropping the KISS byte (a command byte for the radio) then prepending the
length + 4 of the remaining AX.25 packet to be transmitted as a little
endian 16-bit number.  If the high byte of the length has a different
value than the dropped KISS byte users of clones of the skb may observe
this as corruption.  This was observed with by running listen(8) -a which
uses a packet socket which clones transmit packets.  The corruption will
then typically be displayed for as a KISS "TX Delay" command for AX.25
packets in the range of 252..508 bytes or any other KISS command for
yet larger packets.

Fixed by using skb_cow to create a private copy should the skb be cloned.
Using skb_cow also allows us to cleanup the old logic to ensure sufficient
headroom in the skb.

While at it, replace a return of 0 from bpq_xmit with the proper constant
NETDEV_TX_OK which is now being used everywhere else in this function.

Affected: all 2.2, 2.4 and 2.6 kernels.

882e9793fa tg3: Add MDIO bus address assignments
The 5717 is a dual port chip that has a shared MDIO bus design.  While
it is impossible for one function to interface with the wrong phy, that
function still needs to know which MDIO bus address to use when
interfacing with its own phy.  This patch adds code to determine which
MDIO bus address to use.

8d9d7cfc0e tg3: Assign rx ret producer indexes by vector
When RSS is enabled, the status block format changes slightly.  The
"rx_jumbo_consumer", "reserved", and "rx_mini_consumer" members get
mapped to the other three rx return ring producer indexes.  This patch
introduces a new per-interrupt member which identifies which location
in the status block a particular vector should look for return ring
updates.

0c1d0e2b05 tg3: Adjust RSS ring allocation strategies
When multivector RSS is enabled, the first interrupt vector is only used
to report link interrupts and error conditions.  This patch changes the
code so that rx and tx ring resources are not allocated for this vector.
