94a78b79cb bnx2x: Separated FW from the source.
>From now on FW will be downloaded from the binary file using request_firmware.

There will be different files for every supported chip. Currently 57710 (e1) and
57711 (e1h).

File names have the following format: bnx2x-<chip version>-<FW version>.fw.
ihex versions of current FW files are submitted in the next patch.

Each binary file has a header in the following format:


struct bnx2x_fw_file_section {
	__be32 len;
	__be32 offset;
}

struct bnx2x_fw_file_hdr {
	struct bnx2x_fw_file_section init_ops;
	struct bnx2x_fw_file_section init_ops_offsets;
	struct bnx2x_fw_file_section init_data;
	struct bnx2x_fw_file_section tsem_int_table_data;
	struct bnx2x_fw_file_section tsem_pram_data;
	struct bnx2x_fw_file_section usem_int_table_data;
	struct bnx2x_fw_file_section usem_pram_data;
	struct bnx2x_fw_file_section csem_int_table_data;
	struct bnx2x_fw_file_section csem_pram_data;
	struct bnx2x_fw_file_section xsem_int_table_data;
	struct bnx2x_fw_file_section xsem_pram_data;
	struct bnx2x_fw_file_section fw_version;
}

Each bnx2x_fw_file_section contains the length and the offset of the appropriate
section in the binary file. Values are stored in the big endian format.

Data types of arrays:

init_data            __be32
init_ops_offsets     __be16
XXsem_pram_data         u8
XXsem_int_table_data    u8
init_ops             struct raw_op {
                          u8   op;
			__be24 offset;
                        __be32 data;
		     }
fw_version              u8

>From now boundaries of a specific initialization stage are stored in
init_ops_offsets array instead of being defined by separate macroes. The index 
in init_ops_offsets is calculated by BLOCK_OPS_IDX macro:

#define BLOCK_OPS_IDX(block, stage, end) \
       (2*(((block)*STAGE_IDX_MAX) + (stage)) + (end))

Security:

In addition to sanity check of array boundaries bnx2x will check a FW version.
Additional checks might be added in the future.

f85ba78068 tun: add IFF_TUN_EXCL flag to avoid opening a persistent device.
When creating a certain types of VPN, NetworkManager will first attempt
to find an available tun device by iterating through 'vpn%d' until it
finds one that isn't already busy. Then it'll set that to be persistent
and owned by the otherwise unprivileged user that the VPN dæmon itself
runs as.

There's a race condition here -- during the period where the vpn%d
device is created and we're waiting for the VPN dæmon to actually
connect and use it, if we try to create _another_ device we could end up
re-using the same one -- because trying to open it again doesn't get
-EBUSY as it would while it's _actually_ busy.

So solve this, we add an IFF_TUN_EXCL flag which causes tun_set_iff() to
fail if it would be opening an existing persistent tundevice -- so that
we can make sure we're getting an entirely _new_ device.

683703a26e drop_monitor: Update netlink protocol to include netlink attribute header in alert message
When I initially implemented this protocol, I disregarded the use of netlink
attribute headers, thinking for my purposes they weren't needed.  I've come to
find out that, as I'm starting to work with sending down messages with
associated data (like config messages), the kernel code spits out warnings about
trailing data in a netlink skb that doesn't have an associated header on it.  As
such, I'm going to start including attribute headers in my netlink transaction,
and so for completeness, I should likely include them on messages bound from the
kernel to user space.  This patch adds that header to the kernel, and bumps the
protocol version accordingly

82598 and 82599 do not support SFP 1G modules.  Instead of allowing the

78b1f6070f igb: always use adapter->itr as EITR value
The igb driver was switching between adapter->itr containing the EITR value
and the number of interrupts per second.  This resulted in high latencies
being seen after brining the interface down and then back up.  To resolve
the issue the itr value will now only contain the value that should be
programmed into EITR.

41f8910040 bonding: ignore updelay param when there is no active slave
Pointed out by Sean E. Millichamp.

Quote from Documentation/networking/bonding.txt:
"Note that when a bonding interface has no active links, the
driver will immediately reuse the first link that goes up, even if the
updelay parameter has been specified (the updelay is ignored in this
case).  If there are slave interfaces waiting for the updelay timeout
to expire, the interface that first went into that state will be
immediately reused.  This reduces down time of the network if the
value of updelay has been overestimated, and since this occurs only in
cases with no connectivity, there is no additional penalty for
ignoring the updelay."

This patch actually changes the behaviour in this way.

434e7b0d12 net: fix fsl_pq_mdio driver to use module_init()
Modules are not supposed to use any of the *_initcall*() hooks as
the entry point.  fsl_pq_mdio.c was using subsys_initcall_sync()
instead of module_init() to guarantee that the MDIO bus was initialized
before the Ethernet driver goes looking for the phy.  However, the recent
OF helpers rework happens to also make sure PHY connection is deferred to
.open time, so using an initcall is no longer necessary.

This patch replaces the initcall with a more traditional an accepted
module_init() call.

9274498953 net: add Xilinx ll_temac device driver
This patch adds support for the Xilinx ll_temac 10/100/1000 Ethernet
device.  The ll_temac ipcore is typically used on Xilinx Virtex and
Spartan designs attached to either a PowerPC 4xx or Microblaze
processor.

At the present moment, this driver only works with Virtex5 PowerPC
designs because it assumes DCR is used to access the DMA registers.
However, the low level access to DMA registers is abstracted and
it should be easy to adapt for the other implementations.

I'm posting this driver now as an RFC.  There are still some things that
need to be tightened up, but it does appear to be stable.

Derived from driver code written by Yoshio Kashiwagi and David H. Lynch Jr.

Tested on Xilinx ML507 eval board with Base System Builder generated
FPGA design.

- Cleanup handling of phy_map[] entries; they are already NULLed when

  to clear them out when unregistering.
- Split phy_device registration out into a new function so that the

09488e2e0f af_iucv: New socket option for setting IUCV MSGLIMITs
The SO_MSGLIMIT socket option modifies the message limit for new
IUCV communication paths.

The message limit specifies the maximum number of outstanding messages
that are allowed for connections. This setting can be lowered by z/VM
when an IUCV connection is established.

Expects an integer value in the range of 1 to 65535.
The default value is 65535.

The message limit must be set before calling connect() or listen()
for sockets.

If sockets are already connected or in state listen, changing the message
limit is not supported.
For reading the message limit value, unconnected sockets return the limit
that has been set or the default limit. For connected sockets, the actual
message limit is returned. The actual message limit is assigned by z/VM
for each connection and it depends on IUCV MSGLIMIT authorizations
specified for the z/VM guest virtual machine.

(native) iucv message is used.

This patch provides the cmsg interface for iucv_sock_recvmsg() and
iucv_sock_sendmsg().  Applications can use the msg_control field of
struct msghdr to set or get the target class as a
"socket control message" (SCM/CMSG).

b8942e3b6c af_iucv: Support data in IUCV msg parameter lists (IPRMDATA)
The patch allows to send and receive data in the parameter list of an
iucv message.
The parameter list is an arry of 8 bytes that are used by af_iucv as
follows:
	0..6  7 bytes for socket data and
	   7  1 byte to store the data length.

Instead of storing the data length directly, the difference
between 0xFF and the data length is used.
This convention does not interfere with the existing use of PRM
messages for shutting down the send direction of an AF_IUCV socket
(shutdown() operation).  Data lenghts greater than 7 (or PRM message
byte 8 is less than 0xF8) denotes to special messages.
Currently, the special SEND_SHUTDOWN message is supported only.

To use IPRM messages, both communicators must set the IUCV_IPRMDATA
flag during path negotiation, i.e. in iucv_connect() and
path_pending().

To be compatible to older af_iucv implementations, sending PRM
messages is controlled by the socket option SO_IPRMDATA_MSG.
Receiving PRM messages does not depend on the socket option (but
requires the IUCV_IPRMDATA path flag to be set).

Sending/Receiving data in the parameter list improves performance for
small amounts of data by reducing message_completion() interrupts and
memory copy operations.

af88b52def af_iucv: sync sk shutdown flag if iucv path is quiesced
If the af_iucv communication partner quiesces the path to shutdown its
receive direction, provide a quiesce callback implementation to shutdown
the (local) send direction. This ensures that both sides are synchronized.

42e1b4c2c6 iucv: provide second per-cpu IUCV command parameter block
Some of the IUCV commands can be invoked in interrupt context.
Those commands need a different per-cpu IUCV command parameter block,
otherwise they might overwrite an IUCV command parameter of a not yet

04fe20372e mac80211: calculate maximum sleep interval
The maximum sleep interval, for powersave purposes, is
determined by the DTIM period (it may not be larger)
and the required networking latency (it must be small
enough to fulfil those constraints).

This makes mac80211 calculate the maximum sleep interval
based on those constraints, and pass it to the driver.
Then the driver should instruct the device to sleep at
most that long.

Note that the device is responsible for aligning the
maximum sleep interval between DTIMs, we make sure it's
not longer but it needs to make sure it's between them.

Also, group some powersave documentation together and
make it more explicit that we support managed mode only,
and no IBSS powersaving (yet).

1d4df3a50f mac80211: fix variable truncation on 32-bit
Stephen Rothwell reported these warnings from a 32-bit build:

  net/mac80211/mlme.c:1771: warning: left shift count >= width of type
  net/mac80211/mlme.c:1772: warning: left shift count >= width of type
  net/mac80211/mlme.c:1773: warning: left shift count >= width of type
  net/mac80211/mlme.c:1774: warning: left shift count >= width of type
  net/mac80211/mlme.c:1775: warning: left shift count >= width of type

This shows a bug in my code -- BIT(X) uses just "1 << X" which means
a 32-bit integer on 32-bit platforms, but the code here needs a u64
on all platforms. Fix this by using "1ULL << X" instead of BIT(X).

Thanks Stephen!
